⭐ Aquafaba (Best Fat-Free Option)
3 tablespoons per eggAquafaba, the liquid from cooked chickpeas, contains proteins and starches that mimic egg whites' emulsifying and binding properties. It helps set the custard but lacks the richness of egg yolks.
Whisk aquafaba well before use to incorporate air and improve texture. Because it is less rich, consider increasing cream slightly to compensate.
The custard will be lighter and less rich, with a slightly different mouthfeel, but still smooth and creamy enough for Crème Brûlée.
