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.
