By using the bain-marie technique, boil Milk, Egg Yolk, and Sugar until it turns into a custard-like thickness and set aside.

In a saucepan, bring to boil the strawberry puree and sugar, mixing it gradually.

While waiting for the strawberry puree to boil, soak the gelatin powder into a bowl of hot water and make it melt in the microwave oven for about 30 seconds.

Put the whipping cream in a mixing bowl then add the melted gelatin, strawberry puree mixture, chopped fresh strawberries and custard mixture.

Stir using a spatula until it turns into a mousse.

Place the mousse in a heart-shaped mould and refrigerate for at least 3 to 4 houRS
