Brussels Biscuits

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 large bowl, cream the butter until it resembles thick cream.

  2. Gradually add the flour, sugar, eggs, and salt, mixing well after each addition.

  3. Dissolve the yeast in a little warm water and add it to the mixture.

  4. Knead the dough until smooth, then let it rise in a warm place until doubled in size.

Shape and bake

  1. Shape the dough into biscuits and place them on a baking sheet.

  2. Bake in a preheated oven 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

Flour
Provides the structure that holds the biscuits together as they bake.
Butter
Creams with the sugar and adds richness and tenderness to the crumb.
German yeast
Produces gas during rising, leavening the dough so it becomes light.
Sugar
Sweetens the dough and helps the biscuits brown as they bake.
Eggs
Add structure, richness, and moisture, binding the dough together.

The step that matters

Let the dough rise until doubled. The yeast needs a warm place and enough time to produce gas; underproofed dough bakes dense, while the rise sets the final lightness of the biscuits.
