Description
A Roman cheese‑based emulsion of herbs, oil, vinegar, and garlic.
Technical
The casein micelles in the cheese act as emulsifiers, trapping oil droplets within a protein matrix. Acidification by vinegar lowers the pH to ~4.5–4.8, promoting casein aggregation and stabilizing the emulsion. Adequate shear at ambient temperatures disperses the oil without denaturing the protein, while excessive stirring can break the protein network.
