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 butter barely smell alike, yet cooks put them together in 124,287 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
Provides the structure that holds the cookie shape as it bakes.
Sugar
Adds sweetness and helps the cookies brown and turn crisp.
Butter
Adds fat for a tender, rich texture and carries flavor.
Eggs
Bind the dough and add structure and richness.
Caraway seeds
Add a warm, aromatic flavor that defines the cookie.

The step that matters

Roll out the paste thinly. Thickness controls the texture of the baked cookie. A thin layer dries and crisps as moisture escapes quickly, while a thick piece stays soft and cakey in the centre.

Swap the caraway

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

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Carawaythe original
  4. Capersfits about as well

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