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

What each ingredient does

Flour
Provides starch that sets with heat to give the choux its structure.
Eggs
Add moisture and proteins that set during baking, giving structure and lift.
Butter
Adds fat that tenderises the dough and adds richness to the finished pastry.

The step that matters

Gradually add the beaten eggs. Adding eggs too quickly can make the dough too slack to hold its shape. Beating well after each addition lets the eggs blend fully, giving a smooth dough with the right consistency for piping and rising.

Swap the vanilla

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

  1. Raisinfits better
  2. Vanillathe original
  3. Lemonfits less well
  4. Coconutfits less well

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