Orange Float

Ingredients

Directions

Make the lemon syrup

  1. Bring 1 quart of water to a boil in a pot.

  2. Add the juice and pulp of 2 lemons and 1 cup of sugar.

  3. Once boiling, stir in 4 tablespoons of cornstarch and let it boil for 10 minutes, stirring constantly.

Assemble and top

  1. Allow the mixture to cool, then pour it over 4 or 5 sliced oranges in a glass dish.

  2. Beat 3 egg whites in a bowl until stiff. Sweeten and flavor the beaten egg whites with vanilla extract to taste.

  3. Spread the beaten egg whites over the top of the orange mixture.

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

What each ingredient does

Cornstarch
Thickens the boiled lemon liquid into a soft, sliceable custard-like layer.
Egg whites
Whipped into a stiff foam that forms the light topping over the orange mixture.
Sugar
Sweetens the lemon mixture to balance its tartness.
Lemons
Provide acidity and fresh citrus flavor to the lemon mixture.

The step that matters

Beating the egg whites until stiff. Egg whites only hold a stable foam if they are free of fat and fully whipped; under-beaten whites collapse and weep, so the topping will not hold its shape on the orange layer.

Swap the lemon

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

  1. Figfits better
  2. Blueberryfits better
  3. Peachfits about as well
  4. Lemonthe original

Fit is the average pairing score against sugar, orange, egg, vanilla. Candidates are from the same food group and used in at least 100 recipes.
