This is the easiest way I've found to make hollandaise sauce. No double boiler or constant whisking required.
Do your prep first. Separate eggs, melt ghee, juice lemon and bring everything to room temperature.
Get out your Cuisinart with the blade attachment.
Place egg yolks, lemon juice, and sea salt in Cuisinart & blend until yolks are bright yellow.
While the Cuisinart if running, slowly drip in melted ghee until you get a thick creamy mixture.
