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

What each ingredient does

Butter: Creams with sugar to trap air, giving the cookies a tender, rich texture.
Sugar: Creams with butter to aid aeration and adds sweetness and gentle browning.
Egg yolks: Add richness, fat and moisture, helping bind the dough and tenderize the crumb.
Cornstarch: Lightens the texture, producing the tender, delicate crumb typical of alfajores.
Baking powder: Releases gas in the oven so the cookies rise and stay light.

The step that matters

Remove cookies immediately from oven. Cookies keep cooking from residual heat on the hot sheet, so leaving them in or on the pan too long can over-brown the bottoms and dry them out.
