Ingredients

Directions

Prepare the isinglass

  1. Soak the isinglass in 1 quart of cold water for 2 hours or overnight, weighted down.

  2. Remove the isinglass from the water and pour 1 pint of boiling water over it.

  3. Add the sugar and lemon juice to the isinglass mixture.

Set and mold

  1. Chill the mixture on ice until it begins to thicken.

  2. Beat the whites of 4 eggs until stiff and fold them into the mixture.

  3. Pour the mixture into cold water-wetted molds and place them on ice.

Serve

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

What each ingredient does

Isinglass
Gelatin-like protein that sets the mixture so it holds its shape when molded.
Eggs
Whites are beaten to add airy lightness, and yolks and whole egg enrich the custard.
Lemon juice
Adds acidity that brightens the sweetness of the sugar.
Sugar
Sweetens the mixture and adds body to the set dessert.
Milk
Forms the base of the boiled custard that accompanies the dessert, adding richness.

The step that matters

Folding in the beaten egg whites. Stiff whites trap air that gives the mousse-like texture. Folding gently keeps that air in; stirring hard deflates the foam. Chilling until the mixture just begins to thicken helps the whites hold their volume when added.

Swap the lemon

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

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