Pro Tips

• To gently reheat, microwave on 30% power in 20-second bursts, whisking in between, to prevent the sauce from breaking or scrambling.
• Ensure your melted butter is hot (around 180°F / 82°C) but not boiling. The heat is essential for cooking the yolks and creating a stable emulsion.
• If your sauce breaks, place a fresh egg yolk in a clean bowl and slowly whisk the broken sauce into it, a little at a time, until it becomes smooth again.
• Store leftovers in an airtight container in the refrigerator for up to 3 days. This sauce does not freeze well.
