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 ↓
Apple Charlotte
Ingredients
Directions
Make the apple mixture
Mix the stewed apples with sugar, lemon rind, and lemon juice.
Soak the gelatin in cold water for 20 minutes.
Add boiling water to the gelatin to dissolve it, then let it cool.
Once cool, mix the gelatin into the apple mixture.
Set and serve
When the mixture begins to thicken, fold in the beaten egg whites.
Pour the mixture into molds lined with lady fingers.
Serve with soft custard poured around the base.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stewed apples
- Provide the main body and fruity flavour of the filling.
- Gelatin
- Sets the apple mixture so it holds its shape when unmolded.
- Egg whites
- Whipped into foam, they lighten the filling and add a airy texture.
- Sugar
- Sweetens the filling and balances the tartness of the apples and lemon.
- Lemon juice
- Adds acidity that brightens the apple flavour.
The step that matters
Fold in the egg whites at the right moment. Egg whites must be folded in only when the mixture begins to thicken. If added too early, the thin mixture deflates the foam; if too late, the gelatin sets before they blend and leaves streaks or lumps.
Swap the apple
How well each one fits the dish's main ingredients (sugar, lemon, gelatin, egg):
- Vanillafits better
- Orangefits better
- Raspberryfits better
- Applethe original
Fit is the average pairing score against sugar, lemon, gelatin, egg. Candidates are from the same food group and used in at least 100 recipes.
