Why it works: Milk and lemon 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 Drift
Ingredients
Directions
Prepare the isinglass
Soak the isinglass in a quart of cold water for 2 hours or overnight, weighted down.
Remove the isinglass from the water and pour 1 pint of boiling water over it.
Make the snow
Add the crushed sugar and lemon juice to the mixture.
Place the mixture on ice until it begins to thicken.
Beat the 4 egg whites to stiff peaks and fold them into the mixture.
Pour the mixture into cold water-wetted molds and place them on ice.
Serve
Serve with a boiled custard made from the 4 egg yolks, 1 additional egg, and the milk.

Sugar and lemon 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
- Isinglass
- Gelatin-like protein that sets the liquid into a firm, wobbly structure as it chills.
- Egg whites
- Beaten to stiff peaks, they trap air and give the dessert its light, airy texture.
- Crushed sugar
- Adds sweetness and helps stabilise the whipped structure.
- Lemon juice
- Adds acidity that brightens the flavour and balances the sweetness.
- Milk
- Forms the base of the boiled custard served alongside the dessert.
The step that matters
Folding the egg whites into the mixture. Once the mixture has begun to thicken on ice, the whites must be beaten to stiff peaks and folded in gently. Overmixing knocks out the trapped air, so the dessert turns dense instead of light.

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