Why it works: Cream and sugar are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Vanilla-cream
Ingredients
Directions
Whip the cream
Whip the cream with the sugar, wine, and beaten egg white until frothy.
Rub the sugar on the lemon rind and pound it until fine before adding to the mixture.
Remove the froth as it rises and drain it on a sieve in a cool place.
Set and mould
Dissolve the isinglass in ½ cup of water and boil for 2‑3 minutes.
Stir the dissolved isinglass into the cream mixture.
Pour the cream into an oiled mold and let it set in a cool place.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream
- Provides richness and body, and holds the light structure once whipped.
- Egg white
- Its proteins trap air when whipped, creating the frothy, light texture.
- Isinglass
- A gelatin-like setting agent that firms the cream as it cools.
- Sugar
- Sweetens the cream and helps stabilise the foam.
- Sherry or sweet white wine
- Adds flavour and a fruity aroma to the cream.
- Lemon rind
- Its volatile oils add a bright citrus aroma.
The step that matters
Stirring the dissolved isinglass into the cream. Isinglass must be fully dissolved and evenly mixed before the cream cools, because it sets as it chills. Lumps or uneven mixing will leave the dessert with patchy firmness.
