Clarified Butter (Best Option)
1 tablespoon per egg yolkClarified butter is pure butterfat with milk solids and water removed, making it an ideal fat for emulsification in Hollandaise sauce. Its liquid state at warm temperatures allows it to blend smoothly with egg yolks and lemon juice, stabilizing the emulsion.
To ensure success, maintain a gentle heat and add the clarified butter slowly while whisking vigorously to prevent the sauce from breaking. Clarified butter also has a higher smoke point than whole butter, reducing the risk of overheating.
Compared to olive oil, clarified butter imparts a richer, more traditional buttery flavor and a silkier mouthfeel, which many consider superior in classic Hollandaise preparations.
