Why it works: Lemon and rose are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 1,174 recipes. Both carry decanal, which smells soap, orange peel. The science ↓

Spunge Biscuits

Oven, in the book's wordsA quick oven

Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Make the batter

  1. Beat the eggs and sugar together for 30 minutes.

  2. Gently mix in the flour, lemon peel or essence, and rose water.

Bake and finish

  1. Flour the pans and fill them halfway with the batter.

  2. Sift pounded sugar over the filled pans.

  3. Bake in a 400°F (200°C) oven until golden.

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

What each ingredient does

Eggs
Whisked with sugar, they trap air that gives the biscuits their light, sponge-like structure.
Finely powdered sugar
Dissolves into the beaten eggs, adding sweetness and helping hold the foam that makes the sponge.
Flour
Sets during baking to give the biscuits their structure once the egg foam is gently folded in.
Lemon peel or essence
Adds bright citrus aroma and flavour to the batter.
Rose water
Adds a delicate floral aroma to the batter.

The step that matters

Gently mix in the flour. Folding rather than stirring keeps the air beaten into the eggs. Overmixing knocks out that air and the biscuits bake up dense instead of light.
