Orange 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 dough

  1. Pound the almonds very fine in a mortar with the whites of eggs.

  2. Rasp the rind off the oranges finely and mix it with the almonds.

  3. Add powdered sugar and mix well.

  4. If the mixture is too thick, add more egg whites and mix again.

Bake

  1. Preheat the oven to 350°F (175°C).

  2. Drop small round pieces of the mixture onto sheets of paper, about half the size of a nutmeg.

  3. Bake until they are a fine brown, then remove and let cool.

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 flavor of the biscuits.
Powdered sugar
Adds sweetness and helps give the mixture a firm, workable body.
Whites of eggs
Bind the ground almonds and sugar into a dough that holds its shape.
China oranges
Add citrus aroma and flavor from the zest.

The step that matters

Adjusting the mixture's thickness. Egg whites are added only as needed. Too little leaves the mixture crumbly and it will not hold shape, while too much makes the drops spread and bake flat. Adding whites gradually lets you reach a soft but shapeable consistency.

Swap the orange

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

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

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