Why it works: Gelatin and cream match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 1,628 recipes. Both carry acetic acid, which smells sour, vinegar. The science ↓
Peach Dessert
Ingredients
Directions
Make the gelatin
Pour 1 pint of boiling water over 1/2 box of gelatin.
Add 2 cups of sugar and the juice of 2 lemons; strain the mixture.
When nearly cold, add 2 beaten egg whites and stir until it begins to jelly.
Assemble and serve
Peel the peaches, remove the pits, and fill them with chocolate creams.
Place the peaches in glasses and pour the gelatin mixture over them.
Set on ice and serve cold with whipped cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatin
- Sets the liquid into a jelly that holds its shape when cold.
- Egg whites
- Beaten in as the gelatin cools, adding airy lightness to the jelly as it sets.
- Sugar
- Sweetens the jelly and balances the sharpness of the lemon juice.
- Lemon juice
- Adds acidity that brightens the sweetness and freshens the flavor.
- Peaches
- Provide the fruit flavor and form the base the jelly is poured over.
The step that matters
Add the egg whites when the gelatin is nearly cold. If the mixture is still hot, the beaten egg whites will cook partly and deflate, and the jelly will not set evenly. Waiting until it is nearly cold keeps the foam stable while the gelatin begins to thicken.
