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 ↓
Chocolate Ice Cream
Ingredients
Directions
Make the custard
Scald the milk in a saucepan.
Gradually add the sugar, beaten eggs, and grated chocolate mixed with a little milk.
Beat the mixture and cook on the gas stove until thick, stirring continually.
Remove from heat and stir in the dissolved gelatin.
Freeze and finish
Let the mixture cool, then pour it into the freezer.
As it begins to set, fold in the cream and whipped cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the custard as they cook and give the ice cream a rich, smooth body.
- Gelatin
- Helps the mixture set firm and keeps the ice cream smooth and stable when frozen.
- Cream
- Adds fat and richness, giving a softer, creamier texture to the frozen ice cream.
- Sugar
- Adds sweetness and lowers the freezing point, keeping the ice cream softer and scoopable.
- Grated chocolate
- Provides the chocolate flavour and some fat that adds to the creamy texture.
The step that matters
Cooking the custard until thick. Cook the egg mixture gently while stirring constantly. Eggs set with heat, so overheating can curdle them, while undercooking leaves the custard thin and unable to thicken properly.
