Biscuits, Princess Amelia

Oven, in the book's wordsA moderate oven

Ingredients

Directions

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

Make the batter

  1. Whisk the egg whites in an earthen pan until thick and snowy.

  2. Add the sugar and mix well.

  3. Gently fold in the flour, powdered sugar, lemon rind, and orange-flower water.

Bake and serve

  1. Drop spoonfuls onto larger paper than sweet biscuits.

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

  3. Remove from paper while hot.

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

What each ingredient does

Egg whites
Whisked to foam, they trap air and give the biscuits their light, airy structure.
Double refined sugar
Sweetens the batter and helps stabilise the whisked foam while it is mixed.
Flour
Provides the structure that holds the biscuits together once the foam is folded in.
Powdered sugar
Adds sweetness and a fine, tender texture to the batter.
Orange-flower water
Adds a floral aroma that flavours the biscuits.

The step that matters

Gently fold in the flour and flavourings. Folding rather than stirring keeps the air whisked into the egg whites. Overmixing deflates the foam, so the biscuits spread flat and turn out dense instead of light.

Swap the orange

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

  1. Raisinfits better

  3. Orangethe original
  4. Blueberryfits about as well

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