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 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 until just set.
Prepare the egg whites
Beat the egg whites until stiff, sweeten and flavor them.
Float the egg whites on boiling milk for about 1 minute.
Assemble and chill
Remove the gelatine from the mold and place it in cold water.
Using a fork, break the gelatine into bits without liquefying it.
Add spoonfuls of the broken gelatine and the egg whites back into the mold, filling it with the remaining soft gelatine.
Let it cool completely.
Serve
Serve on a dish surrounded by custard made from the egg yolks and 1 pint of milk.

Lemon and sugar barely smell alike, yet cooks put them together in 53,532 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
- Gelatine
- Sets the lemon mixture into a wobbly gel that holds the mousse's shape.
- Egg whites
- Whipped to stiff foam, they give the mousse its light, airy texture.
- Sugar
- Sweetens the lemon mixture and the whipped egg whites.
- Lemon juice
- Adds sharp acidity that balances the sweetness and gives the dish its flavor.
- Milk
- Adds liquid and richness to the custard served alongside the mousse.
The step that matters
Using a fork, break the gelatine into bits without liquefying it.. Gelatine that is too warm melts back into liquid and cannot hold air. Soft, partly set pieces keep their gel structure so they fold into the egg white foam and stay distributed through the mousse.

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