Almond Hearts

Oven, in the book's wordsA hot oven

Ingredients

Directions

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

Prepare the batter

  1. Pound the blanched almonds very fine with the whole eggs until smooth.

  2. Add the powdered sugar and lemon zest, mixing well.

  3. Transfer the mixture to a large bowl (12‑quart capacity).

  4. Whisk in the yolks of 24 eggs for 15 minutes.

  5. Add 6 whole eggs and whisk for another 15 minutes.

  6. Repeat with 6 more whole eggs, whisking until thick.

Fold and bake

  1. Whisk the 24 egg whites until stiff peaks form.

  2. Sift the flour and gently fold it into the almond mixture.

  3. Fold in the whipped egg whites carefully.

  4. Butter heart‑shaped tins and place 6 sheets of paper underneath.

  5. Bake in a gentle oven at 300°F (150°C) until set.

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

What each ingredient does

Sweet almonds
Provide the main body and nutty flavour of the batter.
Eggs
Whisked for air and set during baking to give structure.
Powdered sugar
Sweetens the batter and dissolves smoothly into the mixture.
Flour
Adds a little starch to help the batter hold its shape.

The step that matters

Folding in the whipped egg whites. Whites hold air only when whisked to stiff peaks, and over-mixing or stirring them in vigorously deflates the batter. Folding gently keeps the air in, so the cakes rise and stay light.
