Crème Pâtissière, often called pastry cream or simply crème pât, is a rich and creamy custard used in a wide variety of desserts. One of the most common uses for crème pât is as a filling for pastries. It is the star ingredient in classics like éclairs, cream puffs, and mille-feuille. Its rich flavour and stability make it perfect for layering in desserts, ensuring every bite is indulgent and satisfying. It can also be used in fruit tarts, providing a creamy base that pairs beautifully with fresh or glazed fruit.
