Filbert Biscuit

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.

Prepare the almond paste

  1. Boil sweet and bitter almonds in water for 5 minutes, then skin them.

  2. In a mortar, combine the skinned almonds with orange flower water or beaten egg whites and grind to a paste.

Mix and bake

  1. Mix the almond paste with flour, sugar, and beaten egg yolks until well combined.

  2. Fold in the whisked egg whites gently.

  3. Pour the mixture into a well-buttered mold.

  4. Bake in a preheated oven at 350°F (175°C) until cooked, checking for color.

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

What each ingredient does

Almonds
Provide the main body and nutty flavor of the biscuit.
Flour
Adds structure so the batter sets firm rather than collapsing.
Fine white sugar
Sweetens the biscuit and helps it brown as it bakes.
Egg yolks
Add richness and bind the paste into a cohesive batter.
Egg whites
Whisked and folded in, they trap air that lightens the texture and helps it rise.

The step that matters

Folding in the whisked egg whites. Stirring vigorously knocks out the air trapped in the whites, which leaves a dense biscuit instead of a light one. Fold gently with a spatula so the batter keeps its lift.

Swap the orange

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

  1. Raisinfits better
  2. Vanillafits better
  3. Figfits better
  4. Orangethe original

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