A vinaigrette is a salad dressing that's usually made with oil and vinegar. It's often served on top of greens or vegetables.
You've probably had vinaigrette before at a restaurant or a fancy dinner party, but you might not know where it got its name. The word "vinaigrette" comes from the French language, where "vin" means wine (which is related to vinegar) and "aigre" means sour. This makes sense because vinaigrettes are often made with a mix of acidic ingredients like vinegar or citrus juice and oil.
In some cases, people use the word "vinaigrette" more broadly to describe any type of condiment that's made with oil and acid, but in cooking, it usually refers specifically to salad dressings.
A sauce, made of an acidic liquid such as vinegar or lemon juice; oil; and other ingredients, used as a salad dressing, or as a marinade for cold meats.
