Oenogarum/Hydrogarum

Oenogarum was a common component of a Roman meal and in many respects it would resemble a simple salad dressing such as vinaigrette. Pepper, and occasionally other spices, are mixed with fish sauce and oil and then sweetened with wine and sometimes one or more of the syrups described above. Again like vinaigrette, a sauce like this is unstable and needs to be beaten frequently to maintain an emulsion which can be poured over food or used for dipping. It will separate if left to stand
