Notes: Homemade French salad dressing, or vinaigrette, is better and cheaper than almost anything you can buy. A combination of oil and vinegar (vinaigrette is the diminutive of vinaigre, the French word for vinegar), it can be flavored with fresh herbs and minced garlic or shallot. Most recipes call for gradually whisking the oil into the vinegar until the two ingredients are emulsified. This results in a fairly stable vinaigrette, meaning that it will stay combined for a while (though eventually the oil and the vinegar will separate again). But we usually just shake the ingredients in a screw-top jar instead. The dressing wont stay blended as long, but it certainly simplifies the process.
