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

What each ingredient does

Bananas: Roasting browns their sugars and softens them, deepening flavor and giving the base body.
Light brown sugar: Adds sweetness and moisture, and its molasses contributes caramel notes during roasting.
Heavy cream: Its fat makes the ice cream rich and smooth in texture.
Milk: Provides the liquid base, with less fat than cream for a lighter body.
Vanilla bean: Adds vanilla aroma and flavor throughout the base.

The step that matters

Chill the base for at least 4 hours. A thoroughly cold mixture freezes faster in the machine, which forms smaller ice crystals and a smoother texture. Churning a warm base yields a coarser, icier result.
