Why it works: Cream and gelatin 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 ↓

Ingredients
Directions
Prepare
Cut stale sponge cake into slices about ½ inch thick.
Line three molds with the slices, leaving ½ inch space between each slice.
Fill a deep tin pan one-third full of ice or pounded ice.
Set another pan that holds at least four quarts into the ice-filled pan.
Make the cream filling
Whip the cream in a deep bowl until frothy.
Skim the froth into the pan on the ice until all the cream is whipped.
Stir in the powdered sugar, vanilla extract, and gelatin (soaked in cold water and dissolved in boiling water).
Stir from the bottom until the mixture begins to thicken.
Set and serve
Fill the molds with the mixture and set them on the ice for one hour.
Loosen the sides of the molds.
Turn the dessert out onto a flat dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Heavy cream
- Whipped into foam that gives the dessert its light, airy body.
- Stale sponge cake
- Forms the sturdy outer lining that holds the molded cream shape.
- Gelatin
- Sets the whipped cream mixture so it holds its shape when turned out.
- Powdered sugar
- Sweetens the cream and dissolves easily into it without graininess.
The step that matters
Stir in the dissolved gelatin while the cream is cold. Gelatin must be fully dissolved and mixed in evenly before it begins to set, or it forms lumps and weak patches. Keeping the cream cold over ice slows setting, giving time to blend it through without deflating the whipped foam.
