Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Savoy Biscuits, or Ladies' Fingers
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.
Prepare
Preheat the oven to 400°F (200°C).
Line fluted tins with buttered paper or draw the mixture in straight lines on thick paper.
Make and shape the batter
In a bowl, beat the egg yolks and gradually add the powdered sugar, mixing until smooth.
Add the flour gradually and fold in the beaten egg whites until well combined.
Shape the biscuits into fingers, about ¾ inch wide and 4 inches long.
Bake and store
Bake for 8 minutes until lightly golden.
Store the biscuits back to back in pairs.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites give the batter lift and an airy, sponge-like structure.
- Powdered sugar
- Sweetens the batter and dissolves smoothly into the egg yolks for a fine texture.
- All-purpose flour
- Provides the starch and gluten that set the biscuits' structure as they bake.
The step that matters
Folding in the egg whites. Whites hold the air that makes these biscuits light. Folding gently with the flour keeps that air in; stirring hard deflates the batter and yields dense, flat biscuits.
Swap the orange
The recipe marks orange as optional. How well each one fits the dish's main ingredients (egg, sugar, flour, butter):
- Raisinfits better
- Vanillafits better
- Figfits better
- Orangethe original
Fit is the average pairing score against egg, sugar, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
