Ammonia Cookies

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the dough

  1. In a bowl, combine sweet cream and sugar.

  2. Stir in the carbonate of ammonia and salt.

  3. Gradually add flour until the mixture thickens.

Shape and bake

  1. Roll out the dough and sprinkle sugar on top.

  2. Cut out cookies and bake lightly at 350°F (175°C) until just done.

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

What each ingredient does

Sweet cream
Adds moisture and richness, giving the dough its body and a tender crumb.
Sugar
Sweetens the dough and, on top, adds crunch and helps the surface brown.
Carbonate of ammonia
Releases gas as it heats, lightening the dough so the cookies rise and turn crisp.
Flour
Thickens the mixture and provides the structure that holds the cookies together.

The step that matters

Bake lightly until just done. Carbonate of ammonia breaks down in the oven to release gas, which lightens the cookies. Baking too long dries them out and darkens them, so pull them once the edges are set.
