Orange Float

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the custard

  1. In a pot, combine 3 cups of hot water with the pulp of 2 lemons.

  2. Dissolve 4 tablespoons of cornstarch in 1 cup of cold water and add to the pot.

  3. Boil for 15 minutes, stirring constantly.

  4. Remove from heat and stir in 3 beaten egg yolks and 1 cup of sugar.

  5. Cook for a few minutes without boiling, then let cool.

Assemble and bake

  1. Peel and slice 5 oranges thinly and place them in a serving dish.

  2. Pour the cooled custard over the sliced oranges.

  3. In a separate bowl, beat 3 egg whites until stiff, then add 3 tablespoons of sugar and orange juice to taste.

  4. Spread the meringue over the custard and brown in a 350°F (175°C) oven.

Serve

  1. Serve cold.

Lemon and sugar barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Cornstarch
Thickens the custard as it cooks, giving it a smooth, sliceable body.
Egg yolks
Enrich and thicken the custard, adding richness and a smooth texture.
Egg whites
Whipped into stiff peaks to form the meringue topping that browns in the oven.
Sugar
Sweetens the custard and the meringue, and helps the whites hold their structure.
Lemons
Their pulp adds bright acidity and flavor to the custard base.

The step that matters

Cook the custard without boiling after adding the yolks. Egg yolks scramble and can curdle if overheated after being stirred in, so the custard must be cooked gently and only until thick and smooth.

Swap the orange

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

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

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