A Froth to Set on Cream, Custard, or Trifle

Ingredients

Directions

Make the custard

  1. Beat the yolks of the eggs and stir them into the cream in a saucepan.

  2. Heat the mixture over low heat until hot but not boiling, then pour it into a deep dish.

  3. Let it stand for 24 hours.

Make the froth and serve

  1. Sweeten the fruit pulp and beat it with the egg whites until it holds its shape.

  2. Spoon the mixture onto the cream, shaping it to resemble a rock.

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

What each ingredient does

Eggs
Yolks enrich and thicken the cream, while whites whip into a foam that holds the froth's shape.
Cream
Provides richness and body, forming the smooth base the froth sits on.
Damson pulp
Adds fruit flavour and tartness that cuts through the richness of the cream.
Sugar
Sweetens the fruit and helps stabilise the beaten egg whites.

The step that matters

Heating the custard gently. Heat must stay below boiling. Boiling can scramble the egg yolks and curdle the custard, leaving it grainy instead of smooth and thick.

Swap the lemon

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

  1. Vanillafits better
  2. Raisinfits better
  3. Strawberryfits about as well
  4. Lemonthe original

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