Puree the mangoes until silky smooth. If your blender is feeling dramatic, strain the puree to remove any fibrous bits.

Whip the heavy cream with the sugar until soft peaks form. Don’t overdo it—this isn’t butter, it’s mousse!

Stir in lemon juice and a pinch of salt if you’re feeling fancy. Taste and adjust sweetness if needed.

Bloom the gelatin: sprinkle into warm water and stir until completely dissolved (or follow package directions). Let it cool a touch so it won’t melt the whipped cream.

Fold the mango puree into the whipped cream gently, then whisk in the cooled gelatin until everything looks glossy and airy.

Divide into serving bowls or glasses. Chill for at least 1–2 hours so it sets into a light, mousse-y texture.
