How to Make the Recipe

Step 1: Prepare the Simple Syrup

In a small bowl, stir together warm water, lemon juice, and granulated sugar until sugar dissolves. Set aside to cool.

Step 2: Thaw and Blend Raspberries

Thaw frozen raspberries slightly. In a blender or food processor, puree raspberries with granulated sugar and lemon juice until smooth.

Step 3: Bloom the Gelatin

Sprinkle gelatin over 1/4 cup cold water and let it sit for 5 minutes to bloom.

Step 4: Heat Gelatin and Combine

Gently heat the bloomed gelatin in a microwave or over a double boiler until dissolved. Stir into the raspberry puree until fully incorporated. Let the mixture cool to room temperature.

Step 5: Whip the Cream

In a chilled bowl, whip heavy cream with powdered sugar until stiff peaks form.

Step 6: Fold Mousse

Gently fold the cooled raspberry mixture into the whipped cream, being careful to keep it airy and light.

Step 7: Assemble

Quickly dip ladyfingers into the simple syrup and arrange a layer at the bottom of serving glasses or a trifle bowl. Spoon a layer of raspberry mousse on top. Repeat layers, finishing with mousse.

Step 8: Garnish

Top with fresh raspberries and mint leaves just before serving.

Step 9: Chill

Refrigerate for at least 3 hours or until set.

Tips for Making the Recipe

Use fresh lemon juice for the best flavor—bottled juice can be too harsh.
Don’t overmix when folding mousse; keep it light and fluffy.
Chill your mixing bowl and beaters for better whipped cream results.
Make sure the gelatin mixture is cool before folding in to prevent lumps.
Soak ladyfingers briefly in the syrup to avoid sogginess.

How to Serve

Serve raspberry mousse chilled in clear glasses or small bowls to showcase the layers. Garnish with fresh raspberries and mint for a vibrant presentation. This dessert pairs wonderfully with a light dessert wine or a cup of herbal tea.
