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.

Make the batter

  1. Beat the butter until creamy.

  2. Grate the rinds of the oranges, mixing with the sugar until the yellow part is removed.

  3. Crush the sugar to a powder and mix it with the butter.

  4. Add a pinch of salt, flour, egg yolks, and candied orange peel.

  5. Fold in the beaten egg whites until combined.

Bake and serve

  1. Pour the mixture into small buttered molds.

  2. Sift powdered sugar over the biscuits.

  3. Bake in a slow oven at 300°F (150°C) for about 10 minutes.

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

What each ingredient does

Butter
Creams with the sugar to give the biscuits a rich, tender crumb and flavour.
Egg yolks
Add richness and help bind the batter for a tender, set texture.
Egg whites
Whipped and folded in to lighten the batter and help the biscuits rise.
Flour
Provides the structure that holds the biscuits together as they set.
Seville oranges
Their grated rinds add the aroma and bright citrus flavour.

The step that matters

Fold in the beaten egg whites until combined. Folding gently keeps the air beaten into the egg whites, which gives lightness. Overmixing deflates the foam and leaves dense biscuits.

Swap the orange

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

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