Place a 20×15 cm Pyrex dish in the oven at 100°C, so it becomes slightly warm. This will prevent the caramel from cracking.
In a non-stick pan, gradually add the sugar and melt it over low heat until it turns into caramel.
Pour the caramel into the warm baking dish and spread it evenly to cover the bottom.
Return the dish to the oven while you prepare the cream.
In a saucepan, add the KARPOS Pistachio Drink OLYMPOS and the sugar. Just before it comes to a boil, add the semolina and stir constantly over the heat until the mixture thickens.
Remove from heat, add the vanilla powder, and stir well.
Pour the cream over the caramel, cover with plastic wrap, and let the dessert cool completely at room temperature.
Unmold, sprinkle with crushed pistachios, and enjoy.
