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

What each ingredient does

Butter
Creaming with sugar traps air and gives the cake a tender, rich crumb.
Sugar
Creams with butter for structure and adds sweetness and browning.
Sour milk
Supplies moisture and acidity that reacts with the baking soda to help the cake rise.
Baking soda
Reacts with the acid in the sour milk to produce gas that lifts the batter.
All-purpose flour
Provides the structure that sets the cake as it bakes.
Raisins
Add chewy texture and natural sweetness throughout the cake.

The step that matters

Dissolving the baking soda into the sour milk. Baking soda only lifts the cake when it meets acid. Dissolving it fully in the sour milk spreads the reaction evenly, so the batter rises without pockets of soda or a bitter taste.

Swap the raisin

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

  1. Vanillafits better
  2. Raisinthe original
  3. Figfits less well
  4. Coconutfits less well

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