Description
Emulsification of butter and egg yolks to create a rich and creamy hollandaise sauce.
Technical
This technique involves slowly adding melted butter to a mixture of egg yolks and lemon juice while whisking, creating a stable emulsion through the formation of a complex network of lipids and proteins. The key variables are temperature, whisking speed, and butter addition rate. The optimal temperature for this process is between 25°C to 30°C.
