Why it works: Sugar and cream 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 ↓

Directions
Make the custard

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
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, giving the ice cream its body.
- Flour
- Stabilizes the custard so it thickens smoothly and resists curdling.
- Milk
- Forms the liquid base that the eggs and flour thicken into custard.
- Sugar
- Sweetens the base and lowers the freezing point, keeping the ice cream softer.
- Cream
- Adds richness and fat, producing a smoother, creamier texture.
The step that matters
Cook the custard until it thickens. Eggs and flour must be heated enough to thicken the milk, but overheating can scramble the eggs and make the custard grainy. Stirring steadily while it cooks helps keep it smooth.
