Crisco Oil is the one oil that really mixes with vinegar

Crisco vegetable oil was introduced in 1960.

Vinegar is a liquid processed from the fermentation of ethanol in a process that yields its key ingredient, acetic acid. The word “vinegar” derives from the Old French vin aigre, meaning “sour wine.”.

Vinaigrette is a mixture of vinegar and oil, often flavored with herbs, spices, and other ingredients. The addition of a small amount of mustard can help keep the oil and acid in an emulsion.
