Why it works: Pineapple and vanilla match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 911 recipes. Both carry ethyl isobutyrate, which smells fruity, ethereal. The science ↓
Pine-apple Mousse
Ingredients
Directions
Prepare the pineapple
Peel the pineapple and cut a few slices.
Lay the slices in a bowl, sprinkle with powdered sugar and a little rum, then cover and set aside.
Grate the remaining pineapple into a bowl.
Add vanilla, rum, and enough sugar to make it very sweet.
Set the bowl over ice and stir until very cold.
Make the mousse
Whip the cream until it equals three times the bulk of the grated pineapple.
Fill an ice cream mold with the pineapple mixture.
Fit the cover on tightly and seal the joint with a strip of muslin dipped in melted butter.
Freeze and serve
Pack the mold in layers of ice (3 inches deep) and salt (1 inch deep).
Cover with a carpet and place in a cold area for at least three hours.
To serve, turn out the mousse and arrange the reserved pineapple slices and syrup around it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pineapple
- Provides the main flavour and the juicy base that gets frozen into the mousse.
- Whipped cream
- Adds air and richness, giving the mousse a light, creamy texture.
- Vanilla extract
- Adds aroma that rounds out the fruit flavour.
- Jamaica rum
- Adds aroma and lowers the freezing point, keeping the mousse soft rather than hard.
- Powdered sugar
- Adds sweetness and helps soften the frozen texture.
The step that matters
Whipping the cream to the right volume. The cream must be whipped to the stated bulk so it traps enough air to keep the mousse light; under- or over-whipping changes its texture.
