Why it works: Sugar and almond 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 ↓
Boiled Frosting
Ingredients
Directions
Beat the egg whites to a stiff froth.
Combine the sugar and hot water in a saucepan and boil the mixture briskly for 5 minutes.
Test the syrup by dropping it into cold water; it should "jingle" or form threads.
While beating the egg whites, slowly pour the boiling syrup in a small stream.
If desired, add the almonds or hickory nuts for extra flavor.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into a stiff foam that gives the frosting its light, airy structure.
- Granulated sugar
- Dissolved and boiled into a syrup that sets and sweetens the frosting.
The step that matters
Pouring the boiling syrup into the egg whites. The syrup must be hot and poured slowly in a thin stream while beating. This cooks the egg white proteins gently and builds a stable, glossy foam instead of a runny or grainy one.
Swap the almond
The recipe marks almond as optional. How well each one fits the dish's main ingredients (egg, sugar):
- Pecansfits about as well
- Almondthe original
- Chestnutfits about as well
- Milletfits less well
Fit is the average pairing score against egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
