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

What each ingredient does

Corn starch
Thickens the lemon liquid into a sliceable, spoonable custard-like layer as it cooks and cools.
Egg whites
Whipped into a foam that forms a light, airy topping over the oranges.
Sugar
Sweetens the lemon liquid and the beaten egg whites, balancing the citrus acidity.
Lemons
Provide tart citrus juice and pulp that give the float its sharp flavor.
Oranges
Provide the sliced fruit base with sweet citrus flavor and juicy texture.

The step that matters

Stirring the starch mixture. Corn starch must be stirred continuously while the liquid boils so the granules swell evenly and thicken without lumps or scorching on the bottom of the pot.

Swap the lemon

How well each one fits the dish's main ingredients (sugar, corn, orange, egg, vanilla):

  1. Figfits better
  2. Blueberryfits better
  3. Cherryfits better
