Topic
Emulsion & Dairy
Emulsion and dairy covers the sauces and cheeses that hold fat and water together, and the moments when that hold fails. Mayonnaise, hollandaise, melted cheese and browned butter sit in one topic because they are variations on the same structural problem.
Each note names what the structure depends on and, just as deliberately, what to do once it has already broken. A split sauce is the state most cooks are actually in when they go looking, so the recovery step is written out rather than implied.
