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

What each ingredient does

Bananas
Break down when cooked to give the base its soft body and natural sweetness.
Sugar
Adds sweetness and keeps the frozen texture softer by lowering the freezing point.
Pineapple juice
Adds bright, tangy fruit flavor and acidity to balance the sweetness.
Orange juice
Adds citrus sweetness and aroma along with extra liquid for the frappe.
Lemon juice
Adds acidity that sharpens the flavor and keeps the fruit taste lively.

The step that matters

Cool the strained mixture before adding the juices and freezing. A warm base can melt the ice mixture unevenly and form larger ice crystals. Cooling it fully helps the frappe freeze smoothly and keeps its texture even.

Swap the lemon
