Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Apple Fritters
Ingredients
Directions
Prepare the apples
Peel and slice the apples, removing the core with a cutter.
Soak the apple slices in a mixture of wine, sugar, and lemon juice for an hour if desired.
Make the batter
In a bowl, beat the egg whites and yolks separately.
Melt the butter and stir it into the flour with salt.
Add the egg yolks and enough warm milk to create a firm batter.
Rub out any lumps and fold in the beaten egg whites.
Fry and drain
Fry the batter-coated apple slices in boiling lard until browned.
Drain on blotting paper to absorb excess grease.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide the fruit that softens and turns sweet inside the fried batter.
- All-purpose flour
- Forms the structure of the batter that coats and holds the apple slices.
- Butter
- Adds richness and tenderness to the batter as it is stirred into the flour.
- Eggs
- Yolks enrich the batter, and beaten whites are folded in to lighten its texture.
- Lard
- Heating medium that fries the batter quickly to a crisp, browned coating.
The step that matters
Fold in the beaten egg whites gently after removing lumps. Beaten whites trap air that lightens the batter. Overmixing or deflating them makes the coating dense and heavy instead of light and crisp.
Swap the apple
The recipe marks apple as optional. How well each one fits the dish's main ingredients (flour, butter, milk, egg, wine, sugar, lemon):
- Vanillafits better
- Raisinfits better
- Figfits better
- Applethe original
Fit is the average pairing score against flour, butter, milk, egg, wine, sugar, lemon. Candidates are from the same food group and used in at least 100 recipes.
