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 and add richness through their fat and proteins as they cook.
- Corn starch
- Thickens the milk mixture so the base becomes smooth and creamy when heated.
- Gelatine
- Sets the frozen mixture softly, helping it hold its shape and resist icy crystals.
- Cream
- Adds fat for a smoother, richer texture and a more luxurious mouthfeel.
The step that matters
Pour the egg mixture into the hot milk, stirring constantly until cooked. Egg proteins set at around 160°F and can scramble if the mixture is heated too fast or left unstirred. Constant stirring keeps the custard smooth and evenly thickened.
