Half-and-Half with Butter (Best Option)
3/4 cup half-and-half + 1/4 cup melted unsalted butter per 1 cup heavy creamHalf-and-half typically contains about 10-12% fat, which is insufficient alone for Hollandaise Sauce. Adding melted butter raises the fat content close to that of heavy cream (around 36-40%), which is critical for the sauce's stability and mouthfeel. The fat helps stabilize the emulsion of egg yolks and butter in the sauce.
To ensure success, melt the butter gently and combine it thoroughly with the half-and-half before incorporating into the sauce. Avoid overheating to prevent separation. Whisk continuously during cooking to maintain emulsion.
The final Hollandaise will be nearly indistinguishable from one made with heavy cream, with a rich, smooth texture and balanced flavor.
