Why it works: Almond and sugar are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 15,679 recipes. Both carry 1-penten-3-one, which smells fish, pungent. The science ↓

Ingredients
Directions
The book says “a slow oven”. The 300°F in the steps is the modern equivalent, not the book's own figure.
Prepare the almonds
Blanch the almonds, wash, and dry them in a towel.
Chop the almonds very finely and spread them out on a dish to dry for 2-3 days.
Spread a sheet of paper on an oven tin without greasing it.
Pound the almonds.
Shape and bake
Beat the egg whites very stiffly and mix in the pounded almonds and sugar quickly.
Drop teaspoonfuls of the mixture onto the paper, spaced apart.
Lightly touch the tops with a wet brush and place a strip of blanched almond on each.
Bake in a slow oven (300°F/150°C) until hard.
Remove the paper from the tin, turn it upside down, and wet the back of each biscuit with cold water to release them.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Almonds
- Form the bulk of the biscuit, giving body and a rich, nutty flavour.
- Fine sugar
- Sweetens the biscuits and adds structure as it dissolves into the mixture.
- Egg whites
- Whipped stiff to lighten the mixture and give the biscuits their airy, set structure.
The step that matters
Beat the egg whites very stiffly and mix quickly. Stiffly beaten whites trap air that lifts the mixture; overmixing or letting the whites deflate will make the macaroons dense and flat.
Swap the almond
How well each one fits the dish's main ingredients (sugar, egg):
- Pecansfits about as well
- Almondthe original
- Chestnutfits about as well
- Milletfits less well
Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
