Croissant tarts and mille-feuille demand a pastry cream (crème pâtissière) that pipes into sharp ridges without sagging. Translating this French classic into a plant-based kitchen historically resulted in dull textures. Traditional pastry cream relies on egg yolks to bridge fat and water while building a custard-like suspension.
Replacing dairy milk with pure coconut cream restores the rich mouthfeel that egg-free custard typically lacks. To counter the natural tropical fragrance when a neutral profile is preferred, bakers steep lemon peel, toasted vanilla pod, or a pinch of ground almond into the warming liquid.
The emulsion must be cooked across precise temperatures. Heating the cream past 185°F (85°C) without continuous high-shear whisking can break the coconut fats, leaving a greasy film on top of the custard. Working steadily over indirect heat produces a shiny vegan pastry cream that cuts cleanly inside choux pastry or fruit tarts.
