Fruit Mousse

Ingredients

Directions

Prepare the cream and fruit

  1. Whip the cream to stiff peaks and let it drain on a sieve for 10 minutes.

  2. In a separate bowl, beat together the fruit pulp and powdered sugar.

Combine and chill

  1. Gently fold the fruit mixture into the whipped cream.

  2. Let the mixture sit on ice for 10 minutes to blend thoroughly.

  3. Transfer the mixture into a 2-quart mold.

  4. Pack the mold in salt and ice for 2 hours.

  5. If using a brick mold, fill it so that the mixture presses out between the cover and mold to seal it from brine.

Optional Mousse Glace

  1. Line the mold with ice cream for a Mousse Glace.

  2. Fill the lined mold with the whipped cream and pulp mixture.

The flavor team

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.

    Shared aroma: acetic acid (sour, vinegar).

Sugar and lemon 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

Rich cream
Whipped to stiff peaks, it forms the airy, light structure of the mousse.
Fruit pulp
Supplies the fruit flavour and moisture that is folded into the whipped cream.
Powdered sugar
Sweetens the fruit pulp and dissolves easily into it, adding sweetness.
Lemon juice
Adds acidity that brightens the fruit flavour and balances the sweetness.

The step that matters

Folding the fruit mixture into the whipped cream. Stirring vigorously knocks air out of the whipped cream, so the mousse turns dense and loses its lightness. Fold gently so the air bubbles stay trapped.

Swap the lemon

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

  1. Vanillafits better
  2. Strawberryfits better
  3. Raspberryfits better
  4. Lemonthe original

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