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

What each ingredient does

Brown sugar: Adds moisture, chewiness and caramel flavour to the cookies.
Butter: Provides fat for richness, tenderness and spread during baking.
Eggs: Bind the dough and help give the cookies structure as they set.
Potato starch: Replaces wheat flour, adding tenderness and a crisp, light texture.
Matzoh meal: Supplies the dry body that holds the dough together in place of flour.
Chocolate chips: Add melting pockets of chocolate flavour and sweetness throughout the cookies.

The step that matters

Chill the dough. Chilling firms the butter so the cookies spread less in the oven and keep a thicker shape. The dough also hydrates the matzoh and starch meals, giving a better texture and flavour.

Swap the potato
