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

What each ingredient does

Butter
Adds richness and fat, giving the cookies a tender, crisp texture.
Sugar
Adds sweetness and helps the cookies brown as they bake.
Flour
Provides the structure that holds the thin dough together once baked.
Eggs
Bind the dough and help set the thin wafer as it bakes.
Almonds
Add nutty flavour and a crunchy topping to the cookies.

The step that matters

Spread the dough thinly like a wafer. Thin spreading lets the cookies bake quickly and evenly. Thick dough would stay doughy in the middle while the edges over-brown.
