Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Cream
Provides fat and richness, giving the ice cream a smooth, creamy texture.
Sugar
Sweetens the custard and lowers the freezing point, keeping the ice cream softer.
Eggs
Thicken the custard as they cook, adding structure and richness.
Brown bread
Adds toasted, nutty flavor and a fine crumb texture to the finished ice cream.

The step that matters

Stir constantly until it thickens smoothly. Egg proteins set at around 170°F to 180°F, so if the custard overheats or is not stirred, the eggs can curdle and turn grainy instead of forming a smooth, thick base.
