Millefruit 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 icing and mixture

  1. In a bowl, combine the whites of eggs, sugar, and orange‑flower water to make icing.

  2. Add the preserved orange peel, angelica, preserved lemon peel, sweet almonds, and bitter almonds to the icing.

Prepare and decorate

  1. Prepare a baking sheet with three layers of parchment paper.

  2. Use a brush to apply cochineal color to the mixture for decoration.

Dry and cool

  1. Preheat the oven to 350 °F (175 °C) and place the biscuits inside to dry the icing.

  2. Allow the biscuits to cool completely before removing them from the baking sheet.

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

What each ingredient does

Whites of eggs
Bind the mixture and set into a glossy, firm icing as they dry.
Sugar
Adds sweetness and helps the icing dry to a crisp finish.
Sweet almonds
Provide the main body, chew, and mild nutty flavor.
Angelica
Adds chewy texture and a sweet, herbal flavor.
Preserved orange peel
Adds bright citrus aroma and chewy texture.
Preserved lemon peel
Adds sharp citrus acidity and aroma to balance the sweetness.

The step that matters

Drying the biscuits in the oven. The icing sets as its moisture evaporates, so gentle heat dries it through. Too much heat can brown the sugar and egg white or make the surface puff and crack before the centre is dry.

Swap the angelica

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

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Angelicathe original
  4. Tarragonfits about as well

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