Milk Sponge Bread

Ingredients

Directions

Make the sponge

  1. Combine boiling water, sugar, salt, and baking soda in a pitcher.

  2. Let the mixture cool until touchable.

  3. Add flour to make a thick batter.

  4. Beat the batter for 2 minutes.

  5. Place the pitcher in a kettle of hot water, keeping the temperature below scalding until the mixture becomes light.

  6. Add warm milk to the sponge mixture.

  7. Let the sponge rise until very light.

Shape and rise

  1. Shape the sponge into loaves.

  2. Allow the loaves to rise again, ensuring they don't over‑rise.

Make the potato batter

  1. Boil and mash the potatoes.

  2. Mix the mashed potatoes with lukewarm water.

  3. Strain the mixture through a colander.

  4. Add flour to make a thin batter.

  5. Mix in the yeast.

  6. Let the batter rise.

  7. Stir in more flour until you can use a spoon.

  8. Let the dough rise again.

Knead and bake

  1. Knead in enough flour to make a stiff dough.

  2. Let the dough rise a third time.

  3. When the dough is light, shape into loaves.

  4. Let the loaves rise before baking.

The flavor team

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.

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Flour
Forms the thick batter and later the stiff dough that gives the bread its structure.
Milk
Adds moisture and richness, softening the crumb and aiding browning.
Potatoes
Their starch and moisture keep the loaves soft and moist.
Yeast
Produces gas that makes the dough rise and become light.
Baking soda
Reacts with the sugar and warm mixture to add early lift to the sponge.

The step that matters

Keeping the sponge below scalding. Yeast is killed by high heat, so the sponge must stay warm but not hot enough to destroy the yeast and stop it rising.

Swap the potato

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

  1. Arrowrootfits better
  2. Sweet potatofits about as well
  3. Potatothe original
  4. Capsicumfits about as well

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