⭐ Caster Sugar (Best Vegan Option)
1:1 by volumeCaster sugar has finer crystals than granulated sugar, which allows it to dissolve quickly and evenly in the custard mixture. This ensures a smooth texture without graininess. For the brûlée topping, it caramelizes evenly, creating a crisp and uniform crust.
To use caster sugar effectively, ensure it is well mixed into the custard base before baking. When sprinkling on top, use a thin, even layer to achieve the ideal caramelization. Avoid clumping by sifting if necessary.
Compared to granulated sugar, caster sugar produces a nearly identical texture and flavor but with improved dissolution and caramelization, making it the best direct substitute.
