Ingredients for america's test kitchen bread

Precision ingredients transform home baking into restaurant-quality bread with foolproof science-backed techniques.

The flour is non-negotiable here—King Arthur or Bread Flour yields the best oven spring. Kroger's Signature Flour works in a pinch but lacks the gluten strength for optimal rise. Store flour in an airtight container to prevent oxidation, which degrades protein structure over time. The yeast should be fresh—if it's over six months old, reactivate it in warm water before using. For butter, Plugrá or Land O'Lakes unsalted are ideal; avoid salted versions as they disrupt the delicate salt balance in the dough. The milk must be warmed to 110°F to properly activate the yeast without cooking it.

No instant-release yeast? Active dry yeast requires 5-minute activation in warm water with sugar. Substituting whole wheat flour? Replace 20% of all-purpose with whole wheat and add 1 extra tbsp water per cup. For a richer crust, butter can be swapped for lard or shortening, though texture will differ slightly. The foil-seal technique requires heavy-duty aluminum foil—regular foil tears during baking. If you're making a larger batch, scale all ingredients proportionally while maintaining the same hydration ratio (55% total). The cornmeal isn't optional—it prevents sticking during shaping and creates that signature crust texture.

Store unused flour in the freezer for up to 6 months to preserve freshness. The dough can be refrigerated for up to 24 hours before baking, though it loses some oven spring. For longer storage, freeze shaped loaves wrapped in foil for 3 months. When reheating, wrap cooled bread in foil and warm at 300°F for 10 minutes to restore moisture. The foil-sealed method creates a self-steaming environment during the first 20 minutes of baking, which is why proper foil handling is critical—don't skip the overlapping layers or the seal won't hold moisture effectively.

Step-by-step instructions for america's test kitchen bread recipe

Mastering this bread's signature crust and moisture balance requires precision timing and technique.

In a stand mixer fitted with the dough hook attachment, combine the 5 cups all-purpose flour, 1.5 tsp diamond crystal kosher salt, and 0.25 tsp instant-release yeast. Mix on low speed for 30 seconds to blend the dry ingredients evenly. Add the 0.5 cup cold unsalted butter (cut into cubes) and mix on low until the butter is fully incorporated and the mixture resembles coarse crumbs.

This cold butter method creates pockets that develop into tender layers during baking. I like to press the butter pieces between my fingers to ensure even distribution throughout the flour. Add the 1 tbsp granulated sugar and mix for another 30 seconds until fully combined. With the mixer running on low, gradually add the 1 cup whole milk and 1 whole large egg—the dough will begin to come together.

Increase mixer speed to medium and knead for 5-7 minutes until the dough forms a smooth, elastic ball that cleans the sides of the bowl. For the windowpane test, stretch a small piece of dough between your fingers—it should be thin enough to see light through without tearing. If it tears, knead for another 1-2 minutes.

The proper gluten development here ensures a light, airy crumb. I've found that kneading by hand for 8-10 minutes works just as well if you prefer tactile control. Once the dough passes the windowpane test, transfer it to a lightly oiled bowl (use the 1 tbsp corn oil), turning to coat all surfaces. Cover with a damp towel and let rise in a warm place for 1-2 hours or until doubled in size.

Turn the risen dough onto a lightly floured surface and gently deflate it by pressing down with your fists. Divide into 4 equal portions (about 1 pound each) and shape into smooth balls. For the signature crust, place each dough ball seam-side down on a parchment-lined baking sheet dusted with 0.25 cup cornmeal. Cover loosely with a damp towel and let rise for 30-45 minutes until puffy.

Here's the science-backed trick: Preheat your oven to 425°F with a baking stone or inverted baking sheet inside. When ready to bake, use the 1 sheet aluminum foil to create a seal—place a piece of foil over each loaf and press gently to create an airtight seal. This creates steam during the initial baking phase, developing that coveted crust while locking in moisture.

Bake the foil-sealed loaves for 20 minutes at 425°F. Remove the foil and continue baking for 10-15 minutes until the crust is deep golden brown and sounds hollow when tapped on the bottom. The internal temperature should reach 190-195°F—this ensures proper doneness without overbaking.

I always check for doneness by peeling back the crust slightly—it should be crisp and golden, with a moist interior that resists tearing. For that final crust enhancement, immediately sprinkle each loaf with 0.5 tsp coarse sea salt while still hot. Let cool on a wire rack for at least 30 minutes before slicing—this resting period allows the crumb to set properly.

For maximum freshness, store wrapped in plastic at room temperature for 2-3 days or freeze for up to 3 months. The foil-sealed technique preserves moisture for days, making this bread perfect for sandwiches or toast. I recommend slicing with a serrated knife for clean cuts that showcase the beautiful open crumb structure we worked so hard to achieve.

This bread's secret lies in the balance of cold butter development, proper kneading, and the foil-sealing technique—each step working together to create that perfect crust with a juicy interior. The result is a bread that stays fresh longer and delivers superior flavor with every slice.

Make-ahead tips for this dish

Dough Prep Ahead

Mix your dough up to 24 hours in advance and refrigerate it in an airtight container. The cold slows fermentation, giving you more control over the rise when baking. I like to shape the dough into a log, wrap it tightly in plastic wrap, and store it in the fridge.

This method actually enhances flavor development—something I discovered after accidentally leaving dough overnight! 🥖

Foil-Seal Prep

Cut your aluminum foil into 4 equal squares (about 12x12 inches) before baking day and store them in a dry place. When ready to bake, simply place one square over each shaped loaf and press down firmly.

I keep extra foil handy in my baking drawer for quick access. The key is creating a perfect seal—no gaps—to trap steam effectively during the initial baking phase.

Proofing Shortcut

For faster proofing, place your shaped dough balls in a proofing basket or bowl lined with a damp towel, then set it in your oven with the light on (or a proofing box if you have one).

This creates a warm, humid environment that speeds up rising by 30-50%. I've proofed dough this way in just 20 minutes instead of the usual 45 minutes, though texture may be slightly less open.

Baking Timeline

Preheat your oven and prepare your baking stone or sheet 30 minutes before baking—this ensures proper heat distribution. I set a timer for 10 minutes before baking to handle the foil-sealing process without rushing.

The foil-sealed method adds 5-7 minutes to your baking time, but the results are worth it for that perfect crust and moist interior.

Storage Hacks

For maximum freshness, store your baked loaves in a paper bag at room temperature—the paper allows the bread to breathe while retaining moisture better than plastic. I freeze extra loaves by wrapping them individually in foil, then place them in a freezer bag.

When reheating, wrap the cold bread in foil and warm at 300°F for 10-15 minutes until steaming hot—this restores the crust's crispness perfectly. 💫

Make-Ahead Mistakes

Avoid these common errors: Don't refrigerate dough longer than 24 hours—beyond that, the yeast activity slows too much and affects flavor. Never skip the foil-seal step—it's what creates that signature crust and moisture balance.

And always let bread cool completely before storing to prevent condensation from making the crust soggy. I've learned these lessons the hard way through trial and error!
