Why it works: Lemon and milk are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 19,053 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Snow Drifts
Ingredients
Directions
Make the lemon gelatine
Dissolve the gelatine in boiling water.
Mix the lemon juice and sugar together, then add to the gelatine.
Pour the mixture into a mold and let it cool but not completely set.
Make the egg white foam
Beat the egg whites until stiff.
Sweeten and flavor the egg whites.
Float the egg whites on boiling milk for about 1 minute.
Assemble and serve
Remove the gelatine from the mold by placing it in cold water.
Beat the firm gelatine with a fork until it is in small pieces, not liquid.
Add spoonfuls of the broken gelatine and egg whites back into the mold, filling it with the jelly.
Let it cool completely.
Serve on a dish surrounded by a custard made from the yolks of the eggs and 1 pint of milk.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the lemon liquid into a firm jelly that holds its shape when unmolded.
- Egg whites
- Beaten until stiff, they trap air and give the mousse a light, airy texture.
- Sugar
- Sweetens the lemon mixture and the egg whites, balancing the tartness of the lemon.
- Lemon juice
- Adds acidity and bright lemon flavour that cuts through the sweetness.
- Milk
- Gently cooks the floated egg whites and forms the base of the custard that accompanies the dish.
The step that matters
Let the gelatine cool but not completely set before adding the egg whites. If the gelatine is too cold or too firm, it will not blend with the foam and the mousse becomes lumpy; if it is still too hot, the whites collapse and the mixture stays runny.
Swap the lemon

Fit is the average pairing score against sugar, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
