Soak gelatine in cold water. Drain the mango well. Puree with lemon juice and 50 g sugar. Squeeze the gelatine and dissolve carefully in the pot. First stir in some mango puree and then stir into the whole puree.
Chill the mass for 15-20 minutes until it begins to gel.
Whip the cream until stiff and allow the vanillin sugar to trickle in. Carefully fold the cream into the puree. Fill the mango mousse into a flat dish. Cover and chill for at least 4 hours.
Defrost frozen strawberries. Wash and clean fresh strawberries and puree with 1-2 tbsp. sugar. Peel and slice the kiwis. Cut out small flowers as desired.
Using a large moistened tablespoon, cut out egg-shaped cams from the mousse and place them on dessert plates. Serve with strawberry sauce. Decorate with kiwi flowers and mint.
