Why it works: Apple and clove are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 2,774 recipes. Both carry ethyl octanoate, which smells fruity, wine. The science ↓
Apple Biscuits
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the apple pulp
Bake enough apples to produce 1 pound of pulp in a 400°F (200°C) oven until soft.
Pass the baked apples through a fine sieve.
Make the mixture
In a copper pan, combine the apple pulp, sugar, whole egg, and a little essence of cloves.
Whisk the mixture over gentle heat until hot, then remove and whisk until cool.
Whisk the egg whites until stiff peaks form, then fold them into the apple mixture.
Sift in the starch powder and flour, mixing gently.
Bake and finish
Spoon the mixture onto paper and bake in a 350°F (175°C) oven.
Ice the biscuits before baking.

Flour and egg barely smell alike, yet cooks put them together in 106,462 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
- Apple pulp
- Provides the main flavour and moisture, forming the body of the biscuit.
- Egg whites
- Whisked to stiff peaks, they add airy lift and structure to the mixture.
- Whole egg
- Helps bind the mixture and sets during baking to give structure.
- Powdered sugar
- Adds sweetness and helps give the biscuits a tender, delicate texture.
- Starch powder
- Adds lightness and helps set the mixture to a delicate, tender crumb.
- Flour
- Gives the biscuits structure so they hold their shape while baking.
The step that matters
Folding in the egg whites. Stiff egg whites trap air that gives lift. If the mixture is warm when they are folded in, or the whites are overmixed, the foam collapses and the biscuits bake up flat and dense.
Swap the clove
How well each one fits the dish's main ingredients (apple, sugar, flour, egg):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits better
- Clovethe original
Fit is the average pairing score against apple, sugar, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
