Why it works: Milk and wheat are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 2,418 recipes. Both carry (e,z)-2,6-nonadienal, which smells cucumber, melon. The science ↓

Ingredients
Directions
Make the dough
In a bowl, combine the milk, water, and yeast to create a sponge.
Rub the butter and starch together until creamy, then mix into the sponge along with the salt.
Add enough wheat flour to form a medium firm dough.
Allow the dough to rise, then knead it gently.
Shape and bake
Divide the dough into small half-ounce pieces and shape them into rounds.
Place the rounds on pans, let them prove, and then bake until golden.
Finish
Once baked, cut and toast the tops and bottoms before storing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yeast
- Ferments the sponge, producing gas that makes the dough rise and become light.
- Butter
- Adds fat that tenderizes the crumb and gives a rich, savory flavor.
- Potato starch or cornstarch
- Lightens the texture and tenderizes the crumb by diluting gluten development.
- Wheat flour
- Provides gluten structure so the dough holds its shape and supports the rise.
- Milk
- Adds moisture, richness, and some browning from milk sugars during baking.
The step that matters
Toasting the cut rounds after baking. Zwieback must be fully dried and toasted so it turns crisp rather than soft. Under-toasting leaves moisture in the crumb, which makes it stale and chewy in storage.
Swap the potato
How well each one fits the dish's main ingredients (milk, butter, wheat, flour):
- Potatothe original
- Sweet potatofits about as well
- Leekfits less well
- Arrowrootfits less well
Fit is the average pairing score against milk, butter, wheat, flour. Candidates are from the same food group and used in at least 100 recipes.
