Orange Heart Biscuits

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the batter

  1. In a bowl, combine the powdered sugar and egg yolks.

  2. Pound the preserved orange peels into a fine paste.

  3. Pound the sweet and bitter almonds very fine and mix with the orange flower water.

  4. Add the almond mixture to the bowl with sugar and egg yolks.

  5. In a separate bowl, beat the 4 eggs until light and fluffy, then add to the mixture.

  6. Mix everything well with a wooden spoon until the batter is light and puffy.

  7. Gently fold in the sifted flour until just combined.

Bake and serve

  1. Butter the heart-shaped molds and fill them with the batter.

  2. Dust the tops with powdered sugar before baking.

  3. Bake in a preheated oven at 400°F (200°C) until light and cooked through.

  4. Remove from the molds while hot.

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

What each ingredient does

Egg yolks
Add richness and emulsify with the sugar to give the batter body and a tender crumb.
Eggs
Whipped to trap air, which lightens the batter and helps it rise in the oven.
Flour
Provides the structure that sets the biscuit once baked.
Powdered sugar
Sweetens the batter and helps create a fine, tender texture when beaten with the yolks.
Preserved orange peels
Supply concentrated orange flavour and aroma throughout the batter.
Sweet and bitter almonds
Add nutty flavour and body to the batter.

The step that matters

Folding in the flour. Gently folding in the flour keeps the air beaten into the eggs. Overmixing develops gluten and deflates the batter, producing a dense, tough biscuit instead of a light one.

Swap the orange
