Orange Biscuits

Oven, in the book's wordsA slow oven

Ingredients

Directions

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

Prepare

  1. Blanch and finely chop the almonds.

  2. Beat the egg whites until stiff.

Mix and shape

  1. Add the powdered sugar, chopped almonds, and grated orange rind to the egg whites and mix well.

  2. Drop spoonfuls of the mixture onto parchment paper sprinkled with sugar.

Bake

  1. Bake in a cool 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

Egg whites
Whipped into foam, they give the batter lift and structure as it sets.
Almonds
Chopped almonds add body, nutty flavor and a chewy texture.
Powdered sugar
Dissolves easily, adding sweetness and a fine, tender crumb.
Orange rind
Adds a bright citrus aroma from the oils in the peel.

The step that matters

Beat the egg whites until stiff. Stiff whites trap air that gives the mixture lift and structure. Underbeaten whites won't hold their shape, and overbeaten whites turn grainy and collapse, so the cookies spread flat or come out dense.

Swap the orange

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

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