⭐ Cornstarch (Best Gluten-Free Option)
1 teaspoon per 1 cup of creamCornstarch is a pure starch that thickens custards by gelatinizing when heated, providing structure without gluten proteins. This makes it effective for stabilizing the custard while keeping it silky.
Mix cornstarch with a small amount of cold cream before adding to prevent clumping. Avoid overcooking to prevent a gummy texture.
Compared to bread flour, cornstarch yields a smoother but less elastic custard, which can be desirable for a delicate crème brûlée.
