Ingredients You’ll Need

Raspberry Mousse comes together with a handful of fresh, honest ingredients, each playing a vital role in building the finished dish’s luscious texture and vibrant flavor. Here’s what you’ll need, along with a few notes to help you get the very best results each time.

• Powdered gelatin (2 1/3 teaspoons / 1 packet Knox): The secret to that perfect mousse structure—gelatin sets the mousse without weighing it down.
• Cold water (3 tablespoons): Used to bloom the gelatin, ensuring a smooth, lump-free finish.
• Fresh or frozen raspberries (10 oz, about 2 1/2 cups, thawed if frozen): The star! Use ripe, juicy berries for the most intense color and flavor.
• Granulated sugar (1/2 cup): Balances raspberry tartness and sweetens the mousse just right.
• Fresh lemon juice (2 tablespoons): Adds a pop of acidity, brightening up the berry flavor.
• Heavy whipping cream (2 cups): Whips up into a pillowy cloud, giving the mousse its signature airy texture.
• Powdered sugar (1/4 cup): Sweetens and stabilizes the whipped cream.
• Fresh raspberries & extra whipped cream (8-12 raspberries, for garnish): The finishing touch for both look and taste; totally optional, but highly recommended!

How to Make Raspberry Mousse

Step 1: Bloom the Gelatin

Sprinkle the powdered gelatin evenly over the cold water in a small bowl. Let this sit for 5-10 minutes—it’ll absorb the water and expand, so that it will dissolve smoothly into your syrup later. This step makes all the difference between a mousse that’s silky and one that’s clumpy, so don’t rush it!

Step 2: Make the Raspberry Syrup

Combine the raspberries, granulated sugar, and lemon juice in a medium saucepan over low heat. Stir frequently as the berries release their juice and the sugar melts, creating a sweet-tart syrup. Once everything’s nice and syrupy, carefully press the mixture through a fine mesh strainer into a heat-proof bowl to remove those pesky seeds—you’ll get all the smooth flavor with none of the crunch!

Step 3: Dissolve the Gelatin

Transfer your now-seedless raspberry syrup back into the saucepan. Add the bloomed gelatin, and warm it gently over low heat until the gelatin dissolves completely. This is quick—don’t let it get too hot. Then pour the syrup into a clean, large bowl, and set it aside until it’s cool but not cold. If it gets too cold, it may start to set up, which you don’t want until the cream is folded in.

Step 4: Whip the Cream

In a separate bowl, beat the heavy whipping cream with the powdered sugar. Start on low speed until the cream thickens and soft peaks form. Then turn the speed up to medium and beat until stiff peaks appear. The whipped cream should hold its shape when you lift the beaters, but don’t overdo it or you’ll have butter!

Step 5: Fold Cream Into Raspberry Base

Take a quarter of the whipped cream and briskly stir it into the cooled raspberry syrup; this lightens the base. Now, gently fold in the remaining whipped cream in two or three additions, using a broad spatula and a light hand. The goal is to keep the mixture as airy as possible—stop folding as soon as you don’t see any white streaks.

Step 6: Portion and Chill

Spoon or pipe the finished Raspberry Mousse into 4-6 individual serving dishes or glasses. This not only makes it feel special, it also makes serving a breeze. Cover each one and refrigerate for at least two hours, until the mousse is beautifully set and bites come off light and jiggly.

Step 7: Garnish and Serve

Just before serving, top each Raspberry Mousse with a generous swirl of whipped cream and a few plump fresh raspberries. This lift of freshness adds color, flavor, and an invitation to dig right in. Enjoy every bite!

How to Serve Raspberry Mousse

Garnishes

Fresh garnishes can transform Raspberry Mousse from lovely to absolutely show-stopping. Try dollops of whipped cream, a sprig of mint, a scattering of fresh raspberries, or even a drizzle of raspberry coulis. A few curls of white chocolate make it extra decadent and party-ready.

Side Dishes

Since Raspberry Mousse is light and fruity, it pairs well with crisp cookies like almond tuile, biscotti, or delicate sugar wafers. A platter of mixed berries or a simple shortbread on the side works wonders for both flavor and texture contrast.

Creative Ways to Present

For special occasions, serve Raspberry Mousse in champagne flutes, martini glasses, or even small jars for a fun, portable twist. Add layers with crumbled meringue or cookie crumbs for a parfait-style dessert, or top with edible flowers for an extra splash of color. Let your imagination and the event guide you!

Make Ahead and Storage

Storing Leftovers

If you happen to have extra Raspberry Mousse (lucky you!), simply cover the dishes tightly with plastic wrap and keep them in the refrigerator. They’ll stay fresh and delicious for up to 2-3 days, making them great for prepping ahead or enjoying as a sweet snack later in the week.

Freezing

Raspberry Mousse can be frozen, although the texture will become more like a semifreddo than a classic mousse. Freeze in covered containers, then thaw in the fridge for a few hours before eating. The whipped cream may lose a bit of its airy texture, but the flavor remains irresistible!

Reheating

Mousse is best enjoyed cold, so reheating isn’t needed or recommended. If you froze your Raspberry Mousse, let it thaw in the refrigerator before serving. A good stir can help if it’s separated a touch, and a fresh garnish on top will perk it right up.

FAQs

Can I use frozen raspberries to make Raspberry Mousse?

Absolutely! Just be sure to let them thaw completely and drain off excess juice first. Frozen berries are often picked at peak ripeness, so they’ll provide bold color and flavor—no need to splurge on fresh if they’re out of season.

Is there a vegetarian alternative to gelatin?

Yes, you can swap gelatin for agar-agar, which is a plant-based thickener. Note that agar sets more firmly and quickly than gelatin, so you may need to experiment with ratios to achieve that perfect mousse texture.

Can I make Raspberry Mousse ahead of time?

Definitely! In fact, making it a day in advance allows the flavors to meld. Just keep covered in the fridge and add garnishes right before serving for the freshest look and taste.

Why is my mousse not setting?

The most common culprit is not letting the gelatin bloom fully or dissolving it properly. Make sure to follow the blooming step carefully, and ensure the gelatin mixture is fully melted into the syrup before cooling and folding in the cream.

Can I use another fruit instead of raspberries?

Sure! This recipe is versatile—blackberries, strawberries, or even mango work beautifully. Just adjust the sugar to taste, as some fruits are sweeter or more tart than others.

Final Thoughts

I have a feeling that once you try this Raspberry Mousse, it might just become a new favorite in your dessert repertoire. Whether you serve it for a special gathering or treat yourself on a quiet evening at home, the blend of tangy berries and airy cream is simply irresistible. Give it a go—you’ll be amazed at how something so simple can feel so special!
