Why it works: Sugar and gelatin are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 2,778 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Hamburg Cream
Ingredients
Directions
Prepare
Separate the eggs.
Beat the yolks until light, then add ⅓ cup sugar and beat until very light.
Beat the egg whites until light and stiff.
Combine lemon juice and remaining sugar.
Soak the gelatin in ¼ cup cold water for 30 minutes.
Make the cream
Heat until the sugar dissolves and the mixture reaches boiling point.
Add the gelatin to the boiling mixture.
Stir until it reaches boiling point again.
Carefully stir in the yolks and sugar mixture, cooking until it begins to thicken.
Add the grated lemon rind and remove from heat.
Fold in the beaten egg whites a spoonful at a time, beating constantly.
Set and serve
Quickly pour the mixture into a mold (earthenware is best).
Let it cool.
Serve with or without whipped cream.

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
- Eggs
- Yolks thicken the custard and whites, folded in, give the cream a light, airy texture.
- Gelatin
- Sets the cooled mixture so it holds its shape when turned out or spooned.
- Lemon juice
- Adds acidity that balances the sweetness and brightens the flavour.
- Sugar
- Sweetens the cream and helps the egg yolks thicken smoothly when heated.
The step that matters
Stirring the yolks into the hot mixture. If the hot mixture is added to the yolks too quickly or left to boil hard, the eggs can scramble and become grainy. Stir the yolks in carefully and cook only until the mixture begins to thicken.

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