Ingredients

• 2 cups fresh blackberries
• 3 tablespoons granulated sugar
• 1 teaspoon lemon juice
• 1 teaspoon vanilla extract
• 1 tablespoon water
• 1 teaspoon unflavored gelatin
• 1 cup heavy whipping cream
• 2 tablespoons powdered sugar

Equipment

• Medium saucepan
• Fine mesh sieve
• Mixing bowls
• Hand mixer or stand mixer
• Measuring spoons
• Rubber spatula
• Serving glasses or ramekins

Instructions

1. Prepare the blackberries: In a medium saucepan over medium heat, combine blackberries, granulated sugar, and lemon juice. Stir gently as it warms, letting the berries break down and release their gorgeous juices. This usually takes about 4 to 5 minutes. The aroma is your cue — when your kitchen smells like summer, you’re on the right track.
2. Strain for smoothness: Pour the mixture through a fine mesh sieve into a bowl, pressing the berries with a spoon to get as much purée as possible. This takes a few minutes but it is worth the effort for a silky mousse. Discard the seeds and allow the purée to cool slightly.
3. Bloom the gelatin: In a small bowl, sprinkle the gelatin over one tablespoon of cold water. Let it sit undisturbed for about 5 minutes — this is called blooming and it helps the gelatin dissolve evenly later. Then gently warm it in the microwave for 8 to 10 seconds until it becomes a smooth liquid.
4. Combine and cool: Whisk the warmed gelatin into the blackberry purée along with the vanilla extract. Stir slowly to avoid air bubbles. Let the mixture come to room temperature. Too hot, and it will melt the cream — too cold, and it will clump.
5. Whip the cream: In a mixing bowl, beat the heavy cream and powdered sugar until stiff peaks form. This takes about 3 to 4 minutes with a hand mixer. Look for strong, fluffy peaks that hold their shape — that is your mousse base.
6. Fold gently: Add one-third of the whipped cream to the berry mixture and fold gently with a spatula. This helps loosen the purée. Add the remaining cream and fold until the mixture is uniform. Avoid stirring too hard or fast — you want to keep the mousse airy.
7. Chill and set: Spoon the mousse into serving glasses or ramekins. Tap lightly to settle any pockets of air. Chill in the refrigerator for at least 2 hours until beautifully set and spoonable.
8. Garnish and serve: Just before serving, top with a few fresh blackberries or mint leaves. A curl of lemon zest or a dollop of whipped cream makes it extra special.

Serving and Storage Tips

Blackberry mousse should be refrigerated for at least 2 hours before serving to let it set properly. Once set, it can be kept in the refrigerator for up to 3 days in an airtight container. If you are making it ahead for a party or event, prepare it the day before and store it in individual servings for easy presentation.

This mousse does not freeze well due to its airy texture. Freezing will likely alter the consistency and cause separation when thawed. For the best flavor and experience, enjoy it within a few days of preparation. Leftovers should be kept cold and covered at all times.

Recipe Notes

For extra flavor, use freshly grated Parmesan and do not skip the lemon zest. Leftovers keep well for 2 days in the fridge.
