Why it works: Flour and almond are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

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
Beat the egg yolks with powdered sugar, salt, almond flavoring, and chopped nuts.
Gently fold in the beaten egg whites and sift in the flour gradually.
Use a pastry bag to pipe the mixture onto a baking sheet.
Bake and serve
Bake in a moderate oven at 350°F (175°C) until set but not browned.
Sandwich the drops together with whipped cream, sprinkle with powdered sugar, and serve with cocoa.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Egg and flour 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
- Eggs
- Egg whites provide the airy structure that lifts and sets the sponge drops.
- Pastry flour
- Gives the drops enough structure to hold their shape while keeping them tender.
- Powdered sugar
- Sweetens the batter and helps stabilise the egg foam for a fine, even crumb.
- Chopped nuts
- Add texture and a toasty flavour to the batter.
The step that matters
Folding the egg whites. Egg whites hold air that gives the drops their lift. Folding gently and adding the flour gradually keeps that air from deflating, so the drops stay light rather than dense.
Swap the nuts
How well each one fits the dish's main ingredients (egg, sugar, flour, almond):
- Pistachiofits better
- Cashew nutfits better
- Macadamia nutfits better
- Nutsthe original
Fit is the average pairing score against egg, sugar, flour, almond. Candidates are from the same food group and used in at least 100 recipes.
