Make the dough

  1. Cream together the sugar and butter.

  2. Add the eggs and hot water, mixing well.

  3. Stir in the baking soda and lemon flavoring.

Shape and bake

  1. Roll the dough very thin.

  2. Cut into desired shapes.

  3. Bake at 350°F (175°C) until lightly golden.

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

What each ingredient does

Sugar
Sweetens the dough and helps it crisp and spread as it bakes.
Butter
Adds fat for richness and tenderness, and helps the cookies spread.
Eggs
Bind the dough and add moisture and structure to the cookie.
Baking soda
Reacts with the dough to help it rise and brown.

The step that matters

Roll the dough very thin. Thin dough bakes quickly into crisp snap-style cookies. Thick dough stays soft and cakey in the middle and may not snap when cooled.
