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

What each ingredient does

Flour
Forms the structure of the dough once it is mixed with liquid and kneaded.
Butter
Cold pieces create flaky layers as they melt and steam in the oven.
Egg yolks
Add richness and help bind the dough, giving it a tender texture.
Walnuts
Add crunch and a toasty, nutty flavor to the filling.
Golden raisins
Add chewy sweetness and moisture to the apple filling.
Green apples
Provide moisture, tartness and bulk to the filling.

The step that matters

Keep the butter in tiny cold pieces. Cold butter pockets melt during baking and release steam, which separates the dough into flaky layers. If the butter warms and blends into the flour, the pastry becomes dense instead of flaky.

Swap the apple

How well each one fits the dish's main ingredients (olive, white wine, flour, sugar, egg, butter, raisin):

  1. Vanillafits better
  2. Figfits better
  3. Lemonfits better
  4. Applethe original

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