What holds hollandaise together?
Hollandaise becomes easier to understand when you look at what whisking, egg yolk, and heat are doing inside the sauce.
Exploratorium · Hollandaise: What’s Going On?
Keeping fat dispersed
An emulsion is a mixture in which droplets of one liquid are dispersed through another. In its explanation of hollandaise, the Exploratorium describes egg yolk helping stabilize the mixture while whisking and gradual butter addition divide fat into small droplets.
The sequence has a physical purpose. The sauce depends on building and maintaining a structure, rather than simply combining the right ingredients.
Why understanding the method matters
The Exploratorium also discusses the difference between useful changes in egg proteins and excessive coagulation, when those proteins set too firmly. That helps explain why heat management belongs at the center of the method.
For a cook, this changes the troubleshooting conversation. Instead of remembering only that butter goes in slowly, you can ask what the addition is doing to the mixture. Instead of treating every failure as poor technique, you can consider which part of the structure changed. This archived science explanation offers a way to understand the sauce; an approved recipe and food-safety procedure still govern its preparation.
