⭐ Unsalted Butter (Best Nut-Free Option)
1:1 (1 tablespoon butter per 1 tablespoon coconut oil)Unsalted butter closely matches the fat content and melting behavior of coconut oil, which is crucial for achieving the smooth, rich custard texture in Crème Brûlée. Butter's milk solids also contribute to a slightly richer mouthfeel.
When substituting, ensure the butter is melted and cooled slightly before incorporation to avoid curdling the eggs. Using unsalted butter allows precise control over salt levels, preserving the dessert's delicate balance.
Compared to coconut oil, butter adds a subtle dairy richness without coconut flavor, resulting in a classic Crème Brûlée taste and a smooth, creamy custard.
