Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Make the batter

  1. Beat the egg whites until frothy.

  2. Add the sifted sugar, blanched sweet almonds, and bitter almonds pounded to a paste, then mix all ingredients well.

Bake

  1. Drop spoonfuls onto wafer paper.

  2. Bake in a slow oven at 300°F (150°C).

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

What each ingredient does

Egg whites
Foam traps air when beaten, giving the biscuits a light, airy structure.
Sifted loaf sugar
Sweetens the batter and stabilizes the beaten egg white foam.
Blanched sweet almonds
Provide the main almond body, moisture and a soft, tender texture.
Bitter almonds
Add a strong, distinctive almond aroma and flavor to the biscuits.

The step that matters

Beat the egg whites until frothy. Egg white foam traps air that expands in the oven and gives the biscuit its light structure. Under-beaten whites produce a dense, flat result.

Swap the almond

How well each one fits the dish's main ingredients (egg, sugar):

  1. Pecansfits about as well
  2. Almondthe original
  3. Chestnutfits about as well
  4. Milletfits less well

Fit is the average pairing score against egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
