Why it works: Cream and sugar 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 ↓
Ice Cream Without a Freezer
Ingredients
Directions
Make the custard
Make a smooth custard by combining milk, cream, sugar, eggs, extract, and corn‑starch in a saucepan.
Heat gently until thickened, then cool the mixture.
Freeze
Pour the cooled custard into a tin pail with a tight cover.
Place the tin pail in a larger pail or tub filled with ice and coarse sea salt.
Heap ice around the tin pail and let it freeze for about an hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg proteins thicken the custard as it heats and add richness.
- Cream
- Adds fat, which makes the frozen ice cream smooth and rich.
- Milk
- Provides the liquid base that the custard and ice crystals form in.
- White sugar
- Sweetens the base and keeps the frozen texture softer.
- Corn-starch
- Thickens the custard so it holds body when cooled and frozen.
The step that matters
Heat gently until thickened. Eggs can curdle or scramble if overheated, so the custard should be heated slowly and stirred until it just thickens.
Swap the lemon

Fit is the average pairing score against milk, cream, sugar, egg, corn. Candidates are from the same food group and used in at least 100 recipes.
