Floating Islands

Ingredients

Directions

Make the custard

  1. Beat the yolks of five eggs and the whites of two until light.

  2. Sweeten with five tablespoons of sugar and add flavoring.

  3. Stir into a quart of scalded milk and cook until thickened.

  4. Cool and pour into a glass dish.

Make and set the islands

  1. Whip the remaining three egg whites to stiff peaks, adding three tablespoons of sugar and a little flavoring.

  2. Place this froth over a shallow dish of boiling water to cook it with steam.

  3. Drop spoonfuls of the froth over the custard, spacing them apart.

  4. Optionally, add a teaspoonful of currant jelly on top of each island.

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

What each ingredient does

Egg yolks
Thicken the custard as they cook and give it richness and colour.
Egg whites
Whipped to stiff peaks, they form the light, airy floating islands.
Milk
Forms the liquid base of the custard, which thickens when cooked with the yolks.
Sugar
Sweetens the custard and the meringue, and helps the whites hold their stiff peaks.

The step that matters

Cooking the froth over boiling water. Steaming the meringue gently sets it through without the surface browning or deflating. Cooking the custard only until thickened matters too, since overheated egg yolks can curdle.

Swap the currant

The recipe marks currant as optional. How well each one fits the dish's main ingredients (egg, sugar, milk):

  1. Vanillafits better
  2. Figfits better
  3. Raisinfits better
  4. Currantthe original

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