Question I have made a salad dressing with oil, vinegar, shallots and garlic. How long will it last in my refrigerator?
Answer Hi Sallie,
Home made vinegar and oil salad dressings have a refrigerator shelf life of up to 3 months. After that time the oils begin to take on unpleasant flavors and color changes can occur.
FYI -- flavored oils with whole herbs, garlic, etc should only be refrigerated up to 3-4 days as there have been cases of botulism associated with homemade flavored oils.
Please let me know if I can be of further assistance,
