How do you determine if a sauce has emulsified properly?

• A. It separates quickly into fat and liquid.
• B. The sauce bubbles vigorously during storage.
• C. It appears stable with uniform suspension of fat and liquid; no separation.
• D. It remains completely clear without any fat.

Answer: (C)

A properly emulsified sauce should look uniform and creamy, with fat droplets dispersed evenly throughout the liquid and no visible separation. That steady, creamy appearance means the fat and liquid are held in suspension rather than separating.

If you see the sauce split into a fat layer and a watery layer, the emulsion has broken and is not emulsified. Bubbles forming or persisting during storage aren’t a sign of a good emulsion, and a completely clear sauce with no fat would indicate either no fat was present or all the fat has separated—neither of which shows a stable emulsion.
