Ingredients for america's test kitchen sandwich bread

Precision ingredients transform ordinary flour into artisanal sandwich bread with foolproof crust and airy crumb.

The foundation starts with King Arthur or Bread Flour—their high protein content yields the signature cloud-light crumb and foil-sealed crust. Instant yeast ensures reliable fermentation without activation time, but fresh yeast (tested for activity) delivers superior flavor. For the unsalted butter, use Plugrá or Land O'Lakes for consistent fat content—never salted. The whole milk must be warmed to 90°F to activate the yeast properly; cold milk slows fermentation. Diamond Crystal kosher salt is critical—it dissolves completely, unlike table salt, which can leave grainy residue. Almond flour, though optional, enhances tenderness and extends freshness by 24 hours when included.

No instant yeast? Active dry yeast requires 5-minute activation in warm milk with sugar. Substitute whole milk with 2% milk in a pinch, though texture may be slightly denser. Butter shortages? Use vegetable shortening (same fat content) but expect a marginally less flavorful result. Salt-free? Add 1/4 tsp after baking. For the foil-sealing technique, Reynolds Heavy-Duty Foil works best—its thickness prevents tearing during baking. Cornmeal can be swapped for semolina if preferred, though cornmeal provides a slightly crisper base for the loaf.

Store the baked loaf in an airtight container at room temperature for 3-4 days, or freeze sliced for up to 3 months to prevent staling. The foil-sealed crust stays crisp for 24 hours if wrapped loosely in parchment; beyond that, toast restores freshness. For no-knead method, proof the dough overnight in the fridge for enhanced flavor development. Kneaded dough requires 30-minute rest after mixing to relax gluten—never skip this step or the crumb will be tight.

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

Mastering this technique yields bread with a crisp foil-sealed crust and an impossibly tender crumb.

In a stand mixer fitted with the dough hook attachment, combine the 5 cups all-purpose flour, 0.25 oz instant yeast, 0.125 cup granulated sugar, and 2 tsp diamond crystal kosher salt. Mix on low speed for 30 seconds to distribute the ingredients evenly. This ensures the yeast and sugar make contact for proper activation.

In a separate bowl, whisk together the 1 cup warmed whole milk (90°F), 0.25 cup heavy cream, and 2 room-temperature large eggs. With the mixer running on low speed, gradually pour in the wet ingredients while scraping down the sides of the bowl. Add the 0.5 cup cold cubed unsalted butter and mix until fully incorporated. The dough should begin to come together into a shaggy mass.

Switch to medium speed and knead for 5-7 minutes until the dough becomes smooth and elastic, pulling away from the sides of the bowl. The dough should be slightly tacky but not sticky—if it's too wet, add 1 tablespoon flour at a time until it reaches the right consistency. This kneading develops gluten, which gives the bread its structure and chewiness.

Remove the dough from the mixer and turn it out onto a lightly floured surface. Gently fold in the 0.25 cup almond flour by hand, pressing it into the dough to distribute evenly. This addition enhances the bread's texture, adding a subtle nuttiness and preventing a gummy crumb. Shape the dough into a loose ball and place it in a lightly greased bowl.

Cover the bowl with a damp kitchen towel and let the dough rise in a warm place for 1-1.5 hours, or until it has doubled in size. The dough should feel light and springy when pressed gently with a finger. This first rise allows the yeast to ferment, creating gas bubbles that give the bread its airy texture. Avoid over-rising, as this can lead to a dense loaf.

Punch down the risen dough to release the air, then turn it out onto a lightly floured surface. Divide the dough into 4 equal portions (about 1 pound each) and shape each into a smooth, round ball. Place the balls seam-side up in a greased 9x5-inch loaf pan, spacing them evenly. Cover loosely with the damp towel and let rise for another 45-60 minutes, until the dough has puffed slightly and fills about 75% of the pan.

Here's the thing—this second rise is critical for achieving that cloud-light crumb. The dough should be just slightly underproofed when you bake it; overproofing leads to a collapsed loaf. If the dough rises too quickly, place the pan in the refrigerator for 10-15 minutes to slow the process.

Preheat your oven to 375°F. While the oven heats, dust a baking sheet with 0.25 cup cornmeal—this prevents sticking and adds a subtle crunch to the crust. Remove the loaf pan from the refrigerator (if you chilled it) and carefully transfer the dough to the prepared baking sheet. Gently press down on the dough to ensure it makes full contact with the bottom of the pan.

Cut a 12-inch square from the 1 sheet heavy-duty aluminum foil and place it over the top of the loaf pan, pressing the edges down firmly to create a tight seal. This foil trap creates steam during baking, which develops the bread's signature crisp crust while keeping the crumb tender. Poke a few small holes in the foil to allow steam to escape gradually—this prevents the bread from becoming gummy.

Bake the loaf for 30-35 minutes, until the top is deep golden brown and the internal temperature reaches 190-200°F when measured with an instant-read thermometer. The bread should sound hollow when tapped on the bottom. If the foil starts to bubble excessively, open the oven door slightly to release steam—this ensures even baking.

Remove the bread from the oven and let it cool in the pan for 10 minutes, then transfer to a wire rack to cool completely. The crust will firm up as it cools, and the crumb will become even more tender. Slice the bread with a serrated knife for clean, professional cuts. For the best texture, store the bread in an airtight container at room temperature for up to 3 days, or freeze for longer storage.

Common mistakes when making this dish

Over-Mixing the Dough

I’ve seen so many home bakers turn their perfect sandwich bread into dense, chewy bricks by overmixing the dough. Once you’ve incorporated all the ingredients and the dough starts pulling away from the bowl, stop immediately.

Overmixing develops too much gluten, which creates a tough texture instead of that signature cloud-light crumb. Aim for 5-7 minutes in the mixer—any longer and you’ll regret it. 🌾

Skipping the Rest Period

After mixing, the dough needs a 30-minute rest before shaping. This step relaxes the gluten strands, making the dough easier to handle and preventing a tight, gummy crumb. I’ve made this mistake more times than I’d admit—skipping the rest leads to uneven rises and a less airy texture.

Set a timer and let the dough chill out while you prep the next steps.

Incorrect Proofing Conditions

Proofing is where the magic happens, but too many cooks ruin it with poor conditions. Your dough needs a warm, draft-free environment at 78-80°F to rise properly. If your kitchen is too cold, the yeast will work too slowly, and if it’s too hot, the dough will overproof.

I keep my dough near the oven with the light on (it generates gentle warmth) or use a proofing box. Never proof in a direct heat source—like the oven turned on—which can cook the dough instead of letting it rise.

Underestimating the Foil Seal

The foil-sealing technique is what gives this bread its signature crisp crust, but it’s easy to mess up. If you don’t press the foil tightly against the pan, steam will escape unevenly, leading to a soggy top or uneven browning.

I’ve seen loaves with one side perfectly crisp and the other side still doughy—don’t let that be you! Press the foil firmly, and poke just a few small holes to release steam gradually. This ensures even baking and that perfect foil-sealed crust.

Baking at the Wrong Temperature

Preheating your oven to 375°F is non-negotiable. Too low, and your bread will bake unevenly with a pale, doughy center. Too high, and the crust will burn before the interior is fully cooked.

I’ve learned the hard way that rushing the bake time (like opening the oven door to check too soon) can cause the bread to collapse. Trust the 30-35 minutes guideline and use an instant-read thermometer to confirm the internal temp reaches 190-200°F.

Not Letting the Bread Cool

Patience is key here—transferring your loaf to a wire rack too soon will cause the crust to soften and the crumb to become gummy. Let the bread cool in the pan for 10 minutes first, then move it to the rack.

I know it’s tempting to slice into that warm, golden loaf immediately, but resisting the urge ensures clean slices and the perfect texture. Trust me, the wait is worth it! ⏰
