Half-and-Half with Butter (Best Option)
3/4 cup half-and-half + 1/4 cup melted unsalted butter per 1 cup heavy creamHeavy cream is about 36-40% fat, which is essential for the creamy texture and proper setting of Crème Brûlée. Half-and-half typically contains 10-12% fat, so adding melted butter increases the fat content to approximate heavy cream. This combination ensures the custard remains rich and smooth.
To use, melt the butter gently and whisk it into the half-and-half until fully combined before incorporating into the custard mixture. Ensure the butter is not hot to avoid curdling. Use immediately for best results.
The final custard will be very close in texture and richness to the original made with heavy cream, with minimal flavor difference, preserving the classic silky mouthfeel and proper caramelization on top.
