Ingredients

Directions

Prepare

  1. Mix the red raspberry or currant juice with the sugar.

  2. Press the raspberries through a strainer to remove seeds.

Make the float

  1. Beat the egg whites to a very stiff froth, then gradually add the powdered sugar.

  2. Gradually beat the juice with the sugar and egg mixture until stiff peaks form.

  3. Chill thoroughly on ice.

Serve

  1. Serve in a glass dish half filled with cold cream, and heap the mixture on top in peaks.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Egg whites
Whipped into a stiff foam that gives the float its light, airy structure.
Powdered sugar
Dissolves easily into the whipped whites, stabilising the foam and adding sweetness.
Red raspberry or currant juice
Supplies the fruit flavour and tart acidity, and its liquid is folded into the foam.
Sugar
Sweetens the juice and helps the mixture hold its shape when beaten.
Cold cream
Forms a cool, rich base under the light fruit foam, adding fat and contrast.

The step that matters

Beating the juice into the egg white foam. Adding the juice too quickly or too early can deflate the stiff whites. Adding it gradually keeps the air bubbles intact so the mixture forms stable peaks.

Swap the red raspberry

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

  1. Vanillafits better
  2. Raisinfits better
  3. Strawberryfits better
  4. Red raspberrythe original

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