Why it works: Sugar and cream 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 ↓

Ingredients
Directions
Prepare the gelatine
Cover the gelatine with cold water and let it stand for 30 minutes.
Pour boiling water over the gelatine and stir until dissolved.
Press the stewed apples through a sieve and mix with the gelatine.
Add sugar and stir until it melts.
Squeeze in the lemon juice and mix well.
Set and serve
Pour the mixture into a tin pan and set on ice until it begins to thicken.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the liquid apple mixture into a light, firm structure as it cools.
- Egg whites
- Whipped to foam, they add lightness and airy texture to the set dessert.
- Stewed apples
- Provide the main apple flavour, body and moisture to the sponge.
- Sugar
- Adds sweetness and balances the tartness of the apples and lemon.
- Lemon juice
- Adds acidity that brightens the apple flavour and sharpens the sweetness.
The step that matters
Folding in the egg whites. Whites must be beaten until stiff, then folded gently so the foam is not deflated. Overmixing loses the air that gives the sponge its light texture, and the mixture must be thick but not fully set so the whites stay distributed.
Swap the apple
How well each one fits the dish's main ingredients (sugar, lemon, egg, cream):
- Vanillafits better
- Raspberryfits better
- Orangefits better
- Applethe original
Fit is the average pairing score against sugar, lemon, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
