⭐ Half-and-Half (Best Nut-Free Option)
1:1 substitution (1 cup half-and-half per 1 cup whole milk)Half-and-half combines cream and milk, providing a fat content around 10-12%, which is closer to whole milk's 3.5-4% but with added richness. This helps maintain the emulsion of butter and egg yolks in Béarnaise Sauce, crucial for its smooth texture.
When using half-and-half, gently warm it to avoid curdling and incorporate it slowly to maintain emulsion. Monitor the sauce's thickness as it may thicken slightly more than with whole milk.
The final sauce will be slightly richer and creamier but will retain the classic flavor profile and mouthfeel expected from a traditional Béarnaise.
