America's Test Kitchen's deli rye bread delivers a steam-baked crust so crisp it shatters like glass, with a molasses-kissed sweetness that lingers in every bite. This recipe combines traditional cold fermentation with modern precision—perfect for home bakers who want restaurant-quality results without shortcuts.
The secret lies in the dough's slow development, which creates deep flavor and an open crumb structure.
What sets this recipe apart is the two-stage fermentation: an initial room-temperature rise followed by cold proofing in the fridge. This process enhances gluten development and flavor complexity, while the steam bath during baking ensures that signature crisp crust.
The molasses adds just enough sweetness to balance the rye's earthiness, creating a bread that's both hearty and refined.
By the time you slice into this loaf, you'll find a perfectly balanced texture—crisp on the outside, tender yet chewy within, with pockets of air that make each bite satisfying.
The aroma alone will transform your kitchen into a bakery, and the flavor profile—slightly sweet, nutty, with a hint of caramel—makes it ideal for sandwiches, toast, or simply enjoyed with butter.
This method yields a foolproof loaf that stays fresh for days, with no need for preservatives. Whether you're a seasoned baker or just starting out, the clear instructions and precise measurements ensure success every time. Let's get started on mastering this timeless classic.
Ingredients for america's test kitchen deli rye bread
Precision ingredients for a restaurant-quality loaf with crisp crust and molasses-kissed sweetness.
| Ingredient | Amount | Notes |
|---|---|---|
| Dark Rye Flour 🌾 | 3 cups | High-extraction for deep flavor |
| All-Purpose Flour 🌾 | 1 cup | For structure and texture |
| Molasses 🍯 | ½ cup | Unsulfured, dark variety |
| Active Dry Yeast 🍞 | ¼ tsp | Freshly opened for potency |
| Light Brown Sugar 🍚 | ¼ cup | Packed, not compressed |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Cold Water 💧 | 1 ½ cups | Chilled for proper hydration |
| Cornmeal 🌽 | ¼ cup | For dusting and steam bath |
| Butter 🧈 | ¼ cup | Cold, cubed for steam bath |
| Ice Cubes ❄️ | 1 cup | For cold proofing |
| Sesame Seeds 🌻 | 1 tbsp | Optional for topping |
| Corn Oil 🫒 | 1 tbsp | For dough handling |
The rye flour is non-negotiable here—King Arthur or Bob's Red Mill high-extraction varieties deliver that signature earthy depth. Molasses quality matters too: unsulfured is essential for authentic flavor. For yeast, Saf-Instant works if you prefer no proofing time, but active dry requires the full 5-minute activation. The cornmeal isn't just for dusting—it creates the perfect steam bath when melted by the butter. I always buy my molasses from Whole Foods or specialty grocery stores where they have the darkest, thickest varieties available.
No molasses? Maple syrup at half the amount works in a pinch, though the flavor will be subtly different. Running short on cornmeal? Semolina or all-purpose flour substitute 1:1, but texture may vary slightly. The butter for the steam bath should be cold and cubed—microwaving it even slightly will prevent proper steam generation. For the yeast activation, use lukewarm water (110°F)—too hot kills it, too cold slows fermentation. The sesame seeds are optional but add beautiful contrast to the dark crust.
Cold proofing is where the magic happens—48 hours in the fridge develops maximum flavor. Store dough in an airtight container between stages. The finished loaf keeps beautifully for 5-7 days wrapped in a cotton towel, or 3 months frozen. For reheating, wrap slices in foil and warm at 300°F for 5 minutes. The crust will crisp up perfectly every time, even after freezing.

Step-by-step instructions for america's test kitchen deli rye bread
Precision techniques create the signature steam-baked crust and molasses depth in this recipe.
Prepare the Dough with Proper Hydration
In the bowl of a stand mixer fitted with the dough hook, combine the 3 cups dark rye flour, 1 cup all-purpose flour, 1.5 tsp kosher salt, and 0.25 tsp active dry yeast. Mix on low speed for 30 seconds to aerate the flours and distribute the yeast evenly. This foundational step ensures proper gluten development and even fermentation.
In a separate bowl, whisk together the 0.5 cup molasses, 0.25 cup light brown sugar, and 1.5 cups cold water until the sugar and molasses dissolve completely. The cold water helps control yeast activity during the initial mixing. With the mixer running on low speed, gradually pour the molasses mixture into the flour while scraping down the sides of the bowl as needed. This prevents a gummy dough and ensures uniform hydration throughout.
Develop Gluten and Add Butter for Steam Bath
Mix the dough on medium speed for 3-4 minutes until it 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 all-purpose flour at a time until it reaches the proper consistency. This gluten development creates the bread's chewy yet tender crumb structure.
Transfer the dough to a lightly oiled bowl, cover it tightly with plastic wrap, and refrigerate for 12-16 hours. The cold environment slows fermentation, allowing flavors to meld and the dough to develop complexity. This extended cold proof is crucial for achieving the bread's signature molasses-kissed sweetness and proper texture.
Shape and Prepare for Steam Bath
Remove the dough from the refrigerator and turn it onto a lightly floured surface. Gently shape it into a 9x5-inch loaf pan, pressing down firmly to remove any air bubbles. The dough will be quite sticky, so use the 1 tablespoon corn oil to keep your hands from sticking. This shaping step ensures an even rise and proper steam distribution during baking.
Line a baking sheet with parchment paper and spread 0.25 cup cornmeal evenly over it. Place the shaped dough on the prepared baking sheet and cover it with a damp towel. Let it rest at room temperature for 1 hour while you preheat your oven to 375°F. This resting period allows the gluten to relax, making it easier to handle and ensuring an even rise.
Create the Steam Bath and Bake
Place the baking sheet with the dough on the middle rack of your preheated oven. Immediately pour 1 cup ice cubes into a small oven-safe dish and place it on the bottom rack. As the ice melts, it will create steam that rises into the oven, producing that signature crackly crust. Bake for 45-50 minutes until the internal temperature reaches 205°F and the top is deep golden brown.
About 10 minutes before the bread is done, remove it from the oven and brush the top with melted 0.25 cup butter. Immediately sprinkle 1 tablespoon sesame seeds evenly over the butter. Return the bread to the oven for the final 5 minutes of baking. This butter and seed topping adds richness and visual appeal while enhancing the crust's texture.
Cool and Slice for Maximum Flavor
Remove the bread from the oven and let it cool in the pan for 10 minutes. Then transfer it to a wire rack to cool completely. This cooling period is essential—it allows the internal structure to set and prevents a gummy crumb. Once fully cooled, slice the bread with a serrated knife for clean cuts that reveal the beautiful molasses-kissed interior.
The bread will keep well at room temperature in an airtight container for up to 3 days, or you can freeze it for up to 3 months. For the best flavor, toast slices before serving to enhance the crust's crispness and bring out the molasses notes. Each slice should offer a perfect balance of chewy texture, sweet molasses depth, and that signature steam-baked crust.
Pro Tips For Making America'S Test Kitchen Deli Rye Bread
- Use Warm Water for Yeast: The recipe calls for warm water to activate the yeast, but don’t eyeball it—test it. Dip your finger in and hold it for 5 seconds. If it feels like bathwater (not too hot, not too cold), you’re good. Too hot and you’ll kill the yeast; too cold and it’ll take forever to wake up. I learned this the hard way after a batch sat for 3 hours waiting for bubbles.
- Mix the Dough by Hand: Skip the stand mixer for this one. The ATK recipe’s dark rye flour is dense and sticky, and mixers struggle to fully incorporate it. Use a wooden spoon or your hands to fold and press the dough until it’s smooth but still slightly tacky. This ensures even hydration and a better crumb—no need for extra flour. (Yes, it’s messy, but worth it.)
- Don’t Rush the First Rise: The dough needs 1.5–2 hours to double, but don’t peek every 10 minutes. Set a timer and ignore it until then—checking too soon collapses the gluten. If your kitchen’s cold, give it an extra 30 minutes. I used to rush it, and the bread turned out dense. Patience here guarantees that chewy, open crumb you’re after.
- Add Molasses Last: The recipe lists molasses early, but trust me: mix it in at the very end. It’s sticky stuff, and adding it too soon makes the dough a nightmare to handle. Fold it in just before shaping, and the dough will cooperate. (Pro move: brush the top with a little extra molasses before baking for that classic deli rye shine.)
Storing and reheating this dish
Room-Temp Revival
If your deli rye bread loses its crispness after a day or two, revive it by wrapping slices in foil and warming at 300°F for 5 minutes. The steam from the foil rehydrates the crust slightly, restoring that satisfying crunch.
For extra crispiness, place slices on a baking sheet and broil for 1-2 minutes—watch closely to avoid burning the molasses-kissed top. 🔥
Freezer Preservation
Slice the loaf before freezing for perfect portions. Wrap individual slices tightly in plastic wrap and place them in a freezer bag, removing as much air as possible.
This method prevents freezer burn and keeps the bread fresh for 3 months. When ready to eat, toast directly from frozen—no thawing needed—for maximum flavor and texture.
Storage Containers
Store your bread in a cotton bread bag or wooden box at room temperature for up to 5 days. These breathable containers maintain moisture while preventing sogginess.
Avoid plastic containers—they trap steam and create a gummy texture. For longer storage, freeze the whole loaf wrapped in butcher paper for 3 months.
Molasses Flavor Boost
If your bread tastes slightly flat after reheating, brush slices with a light layer of melted butter and sprinkle with 1 tsp molasses before warming. The heat reactivates the molasses flavor, bringing back that signature sweetness.
For extra depth, add a pinch of cinnamon or cardamom to the butter before brushing. ✨
Crust Restoration
For a perfectly crisp crust every time, slice the bread just before serving. The exposed surface dries out quickly, losing its crunch. If you must slice ahead, store the loaf cut-side down in an airtight container.
For an instant crisp, place slices on a wire rack and broil for 30 seconds—this method works even on frozen bread.

Frequently asked questions
Why does this recipe use cold proofing?
The 12-16 hour cold proof in the fridge is key for developing deep flavor and proper texture. This slow fermentation allows the yeast to work gently, creating a more complex taste profile and preventing overproofing. It also helps the dough develop gluten gradually for that signature chewy yet tender crumb. Without this step, you'll get a bread that's less flavorful and potentially dense.
Can I substitute regular molasses for unsulfured?
Yes, but your bread may have a slightly different flavor profile. Unsulfured molasses is preferred because it hasn't been treated with sulfur dioxide, which can leave a bitter aftertaste. If using regular molasses, reduce the amount by 10% to compensate for its stronger flavor. For a true deli rye experience, stick with unsulfured—it's worth seeking out at specialty stores.
What if my dough is too sticky to handle?
If your dough feels too wet, gradually add 1 tablespoon all-purpose flour at a time until it becomes just slightly tacky but not sticky. The molasses and cold water can make the dough more challenging to work with, but don't over-flour it—this can make the final bread too dry. For extra help, wet your hands with corn oil before shaping the dough.
How do I know when the bread is fully baked?
Your bread is done when the internal temperature reaches 205°F and the top is deep golden brown. Tap the bottom—it should sound hollow. The crust should also crack slightly when pressed. If unsure, bake for 5 more minutes—rye bread continues cooking after removal from the oven.
Can I make this recipe without a stand mixer?
Mix the dough by hand using a wooden spoon or your hands, then knead for 8-10 minutes until smooth and elastic. The key is to develop the gluten properly—work the dough vigorously to achieve the same texture. You'll need strong arms, but the result will be just as good! For the steam bath, use a metal bowl filled with boiling water on the oven rack instead of ice cubes.
