Combine raspberries and white sugar in a small pot. Heat over medium flame, stirring now and then, so the berries soften and release their juice (takes around 5-7 minutes). Push the mixture through a strainer to separate the seeds, leaving smooth puree behind. Fancy a tarter taste? Mix in lemon juice. Let the puree cool down completely before using it.

Want a mousse with more hold? Stir 1 teaspoon plain gelatin into 2 tablespoons of cold water in a small dish. After 5 minutes, microwave it for 5-10 seconds so it melts. Let it cool just a tiny bit, then mix into your raspberry puree once it's at room temperature.

Toss the cold heavy cream, powdered sugar, and vanilla into a sizable bowl. Use an electric mixer to whip until firm peaks form. Don’t go overboard—it might turn lumpy!

Fold the raspberry puree into the whipped cream bit by bit—about a third at a time. Work gently to keep the fluffy texture throughout. If gelatin’s being used, the mousse will set more firmly as it cools.

Transfer the mousse into serving bowls or pretty glasses. Pop them into the fridge for at least 2 hours to chill and firm up. This time also helps the flavors come together nicely.
