Orange Float

Ingredients

Directions

Prepare the oranges

  1. Remove the rind from the oranges and slice them thinly in a glass dish, layering with sugar between each slice. Set aside in a cool place overnight.

Make the syrup

  1. In the morning, squeeze the juice of the lemons into a quart of water and strain it.

  2. Add 1 cup of sugar and bring to a boil.

  3. Slowly stir in 4 tablespoons of cornstarch that has been moistened with water and boil until clear.

  4. Pour the mixture over the oranges and let it cool.

Top and serve

  1. Beat the egg whites to stiff peaks, sweeten with pulverized sugar, and spread over the top.

  2. Garnish with thin slices of red jelly.

  3. Serve with table cream.

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

What each ingredient does

Cornstarch
Thickens the liquid into a clear, sliceable jelly as it boils.
Egg whites
Whipped to stiff peaks, they form a light, airy topping over the dish.
Oranges
Provide the main fruit flavor and, sliced and macerated in sugar, a soft texture.
Sugar
Sweetens the oranges and the syrup, and draws juice out of the fruit.
Lemons
Add acidity that brightens the sweetness of the orange and sugar.

The step that matters

Boil the cornstarch mixture until clear. Cornstarch must be fully boiled to swell and gelatinize, or the mixture stays cloudy and will not set properly. Moisten it with water first so it disperses without lumps.

Swap the orange

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

  1. Vanillafits better
  2. Raspberryfits about as well
  3. Orangethe original
  4. Raisinfits less well

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