Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Egg yolks
- Thicken the custard when gently heated and add richness and a smooth texture.
- Cream
- Adds fat for a rich, smooth mouthfeel and softer frozen texture.
- Sugar
- Adds sweetness and keeps the frozen ice cream from freezing too hard.
- Chestnut flour
- Its starch thickens the base and gives the ice cream its nutty flavour.
- Whipped cream
- Incorporates air into the frozen mixture, making it lighter and less dense.
The step that matters
Stir over heat until thick, then strain. Egg yolks can scramble if the custard gets too hot. Stir gently over moderate heat, and strain to remove any lumps before freezing.
