Whole Wheat Sourdough Sandwich Bread

As a kid I recall more often than not eating baguettes brought home from my Dad’s restaurant, usually procured through a late night call asking for “some bread for tomorrow”. On the weekends my Mom and Grandmother would slice these baguettes at a super slanted angle and make French toast, probably one of the perfect breads for such a thing, but aside from these baguettes we also had a sack of pre-sliced whole wheat bread — which coincidentally also makes great French toast in a different sort of way. It was always whole wheat (even before that was the in thing to buy) and it was mostly just a vehicle for peanut butter & jelly, cinnamon & sugar, straight butter, or whatever other clever things kids can dream up. I always preferred the baguette (and especially these baguettes) with its wonderfully crunchy crust, but there’s a special place for a PB & J sandwich that has so much peanut butter when dropped it would always land on the peanut butter side (imagine a cat always landing on its feet).

“Why don’t we ever have good ol’ sandwich bread?”, I heard my wife recently whisper to herself in the kitchen. This wasn’t the first time I’ve heard such a statement and scattered comments like these got me thinking back about that sliced bread1 I had as a kid. Nostalgia turned to motivation as I felt urged to develop a pan loaf with many of the same characteristics but 100% sourdough, and with somewhere around 98% fewer ingredients — you know, just flour, water, salt and yeast.

whole wheat sourdough sandwich bread in panThe perfect sandwich bread to me is related to that sacked bread from the supermarket, but only in the most remote way possible — perhaps only in the fact that it’s square-ish and sliced. I want a thin and shiny crust with a moist and light interior, a slightly sweet taste not from honey or sugar but from the whole grain itself. And that’s important: I want to actually taste the grain in this bread, not some strange flavor masked by something sweet. The interior should be tight but still light and well fermented, coaxing out maximal flavor from the grain. As far as aesthetics go, you can alter the way this bread rises and opens (or doesn’t open) at the top to suit your taste. I still prefer to impart my signature rustic feel and dark bake, but the final tweaks are up to you.crust and crumb

But first, let’s talk about flour.

Flour Selection

I chose white whole wheat for this recipe because I love the sweet flavor of it, especially compared to red whole wheat which can have a slight bitterness that sometimes pushes through. For the bakes leading up to this post I used Grist & Toll Star White Whole Wheat. I’ve found the flour to be quite strong (in terms of protein) with no gummy flavor to it, which is nice. I recommend using white wheat (King Arthur White Whole Wheat will work well, too) for this recipe but if you don’t have any on hand red wheat will work just fine — the flavor profile will be slightly different but still in the same vein.Grist and Toll flourThe small amount of red whole wheat was mostly used to build my levain (per usual) but also because it does add a slightly strong flavor to the bread, just enough to balance out the sweetness. If you’re more a fan of the white wheat, sub the 10% red for white in the formula below.

If you remember, my recent Spelt Sourdough entry also used type 85 flour and I explained there that this can be approximated by mixing 50% white bread flour with 50% whole wheat. In this formula I’m only using a small percentage so again, feel free to mix whole wheat & bread flour to get the desired quantity or sub it out for another blend.

In the end I really like the flavor and characteristics imparted by these flour choices but it is flexible. I know sometimes we just want to bake bread with what we have in our pantry and not have to go out and pickup special flour — by all means, experiment (and please let me know how your modifications turn out)!

Whole Wheat Sourdough Sandwich Bread Formula

A word of warning upfront: this formula has a very high hydration; the structure of the pan helps keep this dough together and permits me to push water as far as the flour will take it. This amount of water imparts a significantly moist and soft texture to the interior that is typical of sandwich bread, and the results are definitely worth the added hardship of dealing with such a wet dough.

Keep in mind that your flour will act differently with all this water added so hydrate accordingly. Start with a lower percentage and work your way up until you find the perfect point for your flour mix. The dough should be wet looking, extensible and very soft, but it should not be overly “soupy” or falling apart — if this happens hydration is too high for your flour. You can see below what my dough looked like right after mixing.extensible doughAfter a bit of practice this bread becomes easy to make and you can double the formula to make two pans at a time. I see myself making this bread fairly often, freezing one loaf and using the other, this way we always have sliced whole wheat sourdough sandwich bread at the ready.

Total dough weight: 1200g
Pre-fermented flour: 5.00%
Hydration: 100%
Yield: One loaf in a 9” x 5” x 2.75” pan

The USA Pan used for this bake has a silicone coating, and while I lightly oil the pan with olive oil I don’t really think it’s necessary — I have yet to have anything stick to this thing. It’s heavily used here in my kitchen mostly for my sourdough banana bread but now also traditional sandwich bread and even sourdough tea cakes.

Levain Build

25g Giusto’s Stoneground Whole Wheat 50%
25g Central Milling Type 85 50%
50g H2O @ room temperature 100%

I used half Central Milling type 85 and half Giusto’s whole wheat for the levain build, but you can change this up if you’d like (e.g. use 100% whole wheat or 100% white whole wheat) just keep an eye on its fermentation rate as a higher percentage of pure whole wheat will peak much faster.liquid levain

Dough Formula

After a few trials I arrived on a final dough weight of 1200 grams for my bread pan. The resulting bread was nicely sized and perfect for what I’m looking for but I think it could be pushed even further, perhaps somewhere around 1300-1400 grams if you want an even taller loaf, one that rises and slightly spills over the edges.

Note that the baker’s percentages listed below are with respect to the final dough ingredients and do not take into account the levain.

Target final dough temperature (FDT) is 75ºF2.

Weight Ingredient Baker’s Percentage
438g Grist & Toll Star White Whole Wheat 78.95%
73g Central Milling Type 85 13.16%
44g Giusto’s Stoneground Whole Wheat 7.89%
3g Diastatic Malt Powder (optional) 0.53%
555g H2O @ 90ºF 100.00%
14g Fine sea salt 2.47%
73g Mature, liquid levain 13.16%

Method

1. Levain – 9:00 a.m.

Build the liquid levain in the morning and store somewhere around 74-76ºF ambient.

2. Autolyse – 1:00 p.m.

Mix flour, diastatic malt and water (reserve 100g of the total water for later mixing) in a bowl until all dry bits are hydrated. Cover bowl and store somewhere warm (around 75ºF) for 2 hours.

3. Mix – 3:00 p.m.

Due to the high hydration of this dough it’s helpful to build some strength at the start of mixing before adding in the reserved 100g of water.

Add the mature levain and about 25g of the reserved water, mix thoroughly by hand to incorporate and then slap and fold for about 6 minutes, just until the dough starts to show signs of a smooth surface and holds its shape on the counter. If you aren’t comfortable with this method, or don’t like it, you can do stretch and folds in the bowl until your dough tightens up and is slightly hard to stretch out and fold over. Around medium development.

When finished sprinkle the salt on top of the dough and use the remaining 75g of water (or less if the dough is starting to feel too wet and falling apart) to help dissolve. Pinch through a few times and fold the dough over itself to help incorporate. Keep folding the dough until all the water is absorbed and it comes together, it will end up slightly sticky.

Transfer dough to a tub or thick-walled bowl for bulk fermentation.

4. Bulk Fermentation – 3:20 p.m. to 7:00 p.m.

At 74-76ºF ambient temperature bulk fermentation should go for a little less than 4 hours. Watch the dough! With this much whole grain it’s possible your dough could ferment faster than mine.

Perform 5 sets of stretch and folds during bulk, spaced out by 30 minutes (the first set starts 30 minutes after you finish mixing). After the fifth set of stretch and folds, performed gently, let rest for the remainder of bulk. The dough will not rise an incredible amount, but it should be slightly jiggly and some bubbles on top and at the sides. You want to see a slight convex edge between the dough and the bowl.

5. Pre-shape – 7:00 p.m.

Sprinkle a light dusting of flour on your bench and dump out the dough. Shape into a single round mass and let rest 20 minutes uncovered. Because this dough is highly hydrated rely mostly on your bench knife and try to touch the dough as little as possible. I use my knife to pick up and pull the mass around in a circle, forming a relatively tight skin on the dough.preshape and oiled panUsing a little olive oil lightly oil the baking pan.

6. Shape – 7:05 p.m.

Shaping this dough can be challenging. The good news is it’s pretty hard to mess it up, just form it as best you can into a “tube” the width of the baking pan and get it in there with as much tension on the surface as possible. The structure of the pan will force your dough to rise upward whereas with a hearth loaf we’d really have to ensure a proper shape so there’s no spreading in the oven.

Moderately flour the top of the dough and flour the work surface. Flip the resting round over onto the floured surface and fold the side edges at the top up and over to the middle (imagine a round bottom that tapers up to a point at the top, it will look like an inverted diamond of sorts). With floured hands take the point at top and start to roll the entire mass of dough downwards, with each roll pushing the dough with your thumbs inward toward the bench — imagine rolling up a beach towel. At the end of this you’ll have a tube that has essentially been rolled downward. Transfer to your oiled pan with the seam on the bottom.

An alternative shaping method that might be easier to perform is to simply fold the sides slightly up and over towards the middle, then roll up the dough tightly. It won’t be as spread out to the sides, but the dough should relax in the pan overnight.

For more information and photos on shaping, proofing, and scoring pan loaves check out my guide to shaping pan loaves.

7. Rest & Proof – 7:10 p.m.

Cover your pan with plastic and then retard in the refrigerator at 38ºF for 11-12 hours. Even at such cool temperatures this dough can quickly overproof so keep an eye on it in the fridge in the morning.

8. Bake – Next Morning: Preheat oven at 6:10 a.m., Bake at 7:10 a.m.

Preheat oven for one hour at 500ºF.

I did a very rough score on the top of the dough before placing into the oven. If you choose not to score at all you’ll most likely get a taller loaf, and depending on how tight you shaped your dough, there may be more or less of a rupture on top. In the future I’d like to play with an even longer proof in the fridge with no score at all. This should yield an even more tender crumb and hardly any dramatic fissure.scoring doughI cut a rectangular piece of parchment paper and set it directly on my baking surface, just incase the heat was a little too high for the pan to handle.

Spritz the top of the dough in the pan with a hand mister and place it into the oven on the parchment paper. Bake for 20 minutes at 450ºF with steam, and an additional 30 minutes at 450ºF without steam. Then, turn the oven down to 425ºF and cook for an additional 15-20 minutes until done (the internal temperature on my loaf was 205ºF).

With dough at this hydration you have to ensure you bake it fully, otherwise the crumb could be undercooked, slightly gummy and just not baked to its potential. The above times and temperatures are a good starting point but they may vary slightly for your environment (and altitude). If you notice your loaf coloring too fast in the oven lower the temperature 15-20ºF at each step and lengthen the bake time to suit.

I steamed the oven in my usual way, described here in my post on how to steam your home oven for baking. While this extra steam might not have been necessary I wanted to ensure maximal rise and a thin & crisp crust. Remove from the oven and let cool in the pan on a wire rack until cool enough to remove the bread from the pan, then remove and let cool directly on the wire rack for a few hours.

If you cut this bread too soon the interior may not be completely set so give it a little time to relax.

Conclusion

sourdough sandwich bread

With only four ingredients this healthy bread is a daily bread that has a mellow, sweet taste. The crust is supple but not mushy and the keeping qualities from sourdough mean we’ll be done eating this entire thing well before any threat of spoilage. This is unmistakably a bread that can be made every week to satisfy those old fashion sandwich cravings (perfect for kids, too).

Crust

whole wheat sourdough sandwich bread crustThe crust is killer. The intense caramelization is so appetizing it makes your mouth water before you even have a bite. You can see lots of little blisters on the surface of this loaf (thanks in part by the extra steaming in the oven) that provide a little crunch when toasted, a perfect contrast to the extremely tender crumb inside.

Crumb

whole wheat sourdough sandwich bread crumbBread like this asks for a certain level of tightness, it needs to hang on to all those fantastic ingredients you’ll be sandwiching in there. The high level of whole wheat helps ensure a fairly closed crumb but more important is the full level of fermentation. You’ll notice no dense areas, no gummy sections, everything is well fermented and very tender. If you recall at the start that was one of the criteria I had for this bread and it’s readily satisfied.

Taste

Channeling my smørrebrød history I made an open faced sandwich with ripe tomato, basil, goat cheese and extra virgin olive oil — just perfect for this bread after a heavy toasting.tomato, goat cheese, basil and EVOO on sourdough sandwich breadSweet, soft, mellow and contrasting. All part of a bite and all contributing to the grin on my face. I’ve come to really enjoy the flavor of Grist and Toll’s Star White Wheat and I can’t wait to try this recipe with a few other varieties I have, including my own fresh milled white wheat berries. I don’t think you could go wrong with using red wheat instead of white, but as I mentioned previously white wheat has a slightly sweet and more subdued taste that works well with bread like this.


Well, there you have my take on a whole wheat sourdough sandwich bread. I feel like I’ll be tweaking this bread into the future as I already have a few things I’d like to try out: use a large percentage of fresh milled flour, push fermentation even further (perhaps 2-4 more hours for the final proof) and finally increase the dough weight to 1400 grams to see just how high I can get this bread to climb. Some other welcome additions could be a seed or cornmeal topping and heck, even a little cornmeal mixed into the dough to add another level of sweetness.

Oh! I’d be remiss if I talked so highly about that thick slathering of peanut butter and leave without proof. Once this loaf cooled I was waiting knife-in-hand and it was the first thing I concocted, even the photo couldn’t wait.

  1. And baguettes too, and I just posted a recipe for baguettes!

  2. This is a few degrees lower than usual, my slap/fold mixing method ended up cooling off the dough more than expected.
