Here is a recipe to prepare a delicious vanilla pudding with raspberry coulis:

Ingredients:

For the vanilla pudding:

• 500ml of whole milk
• 100g of sugar
• 1 vanilla pod (or 1 teaspoon vanilla extract)
• 4 egg yolks
• 40g of corn starch (cornflour)

For the raspberry coulis:

• 250g of fresh or frozen raspberries
• 50g of sugar
• 1 tablespoon lemon juice

Instructions:

For the vanilla pudding:

1. Preparation of vanilla milk:
   • In a saucepan, pour the milk and add the vanilla pod cut in half lengthwise (or the vanilla extract). Heat the milk over medium heat until it is close to boiling point, then remove from the heat and leave to infuse for about 10 minutes.
2. Preparation of the yolk mixture:
   • In a bowl, beat the egg yolks with the sugar until light and fluffy. Add the cornstarch and mix well until completely incorporated.
3. Milk incorporation:
   • Remove the vanilla pod from the milk (if using). Slowly pour the hot milk into the egg yolk mixture, stirring constantly to prevent the eggs from cooking.
4. Cooking the pudding:
   • Pour the resulting mixture back into the saucepan and cook over medium-low heat, stirring constantly, until the pudding thickens and begins to bubble slightly. Continue to cook for 1-2 minutes, then remove from heat.
5. Cooling down:
   • Pour the pudding into individual cups or one large container. Cover with cling film, making sure the cling film touches the surface of the pudding to avoid a skin forming. Let cool to room temperature, then transfer to the refrigerator for at least 2 hours, or until well chilled.

For the raspberry coulis:

1. Preparation of raspberries:
   • In a saucepan, combine the raspberries, sugar and lemon juice. Cook over medium heat, stirring occasionally, until the raspberries break down and the mixture thickens slightly, about 10 minutes.
2. Filtering:
   • Pass the raspberry mixture through a fine mesh strainer to remove the seeds, resulting in a smooth sauce.
3. Cooling down:
   • Let the coulis cool to room temperature, then store it in the refrigerator until ready to serve.

Assembly:

1. Service:
   • Just before serving, pour the raspberry coulis over the vanilla pudding in individual cups. You can decorate with some fresh raspberries and a mint leaf for a finishing touch.

This vanilla pudding with raspberry coulis is an elegant and delicious dessert, perfect for finishing a meal in a refined way. Enjoy your meal!
