Orange Biscuits

Oven, in the book's wordsA moderately hot oven

Ingredients

Directions

The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Combine the grated orange rind, ground almonds, powdered sugar, and egg whites in a mortar.

  2. Mix well with a pestle until the mixture is very light.

Shape and bake

  1. Drop small lumps, about the size of a walnut, onto double paper on a baking tin, spacing them apart.

  2. Bake in a moderate oven at 350°F (175°C) until done.

  3. Remove from the oven and let cool before taking them off the paper.

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

What each ingredient does

Orange rind
Adds the characteristic citrus aroma and flavor to the biscuits.
Sweet almonds
Provide fat and body, giving the biscuits a tender, rich texture.
Powdered sugar
Sweetens the biscuits and dissolves easily into the egg mixture.
Egg whites
Bind the mixture and, when beaten light, help the biscuits rise and set structure.

The step that matters

Beat until very light. Whipping the mixture with a pestle incorporates air, which gives the biscuits lift and a tender crumb. Under-mixing leaves them dense and heavy after baking.

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.
