Zwieback for Infants

Ingredients

Directions

Make the sponge

  1. In a bowl, combine the milk, yeast, and enough flour to create a soft sponge.

  2. Let the sponge rest until it begins to break.

Shape and bake

  1. Add the remaining ingredients and mix to form a dough.

  2. Shape the dough into a long loaf.

  3. Let the loaf rise until it doubles in size.

  4. Bake the loaf until golden brown.

  5. Allow the baked loaf to rest for 24 hours.

Slice and toast

  1. Slice the loaf as you would for plain Zwieback, sprinkle with sugar and a little cinnamon.

  2. Toast until light brown.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Forms the gluten structure that holds the loaf and its crumb together.
Yeast
Ferments the sponge, producing gas that makes the loaf rise.
Milk
Adds moisture and softness to the dough and helps browning.
Butter
Adds fat, which tenderizes the crumb and adds richness.
Sugar
Feeds the yeast and adds sweetness and browning during baking and toasting.

The step that matters

Let the baked loaf rest for 24 hours. Resting lets moisture redistribute through the crumb, so the loaf firms up and slices cleanly instead of crumbling when cut and toasted.

Swap the anise

How well each one fits the dish's main ingredients (flour, milk, butter, sugar):

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Jalapenofits better
  4. Anisethe original

Fit is the average pairing score against flour, milk, butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
