This vinaigrette recipe is from my childhood. It was always on the table to be served over a green salad. For many years I thought it was my grandfather's recipe because he was a French chef by profession. But, as an adult I learned from my mother that it was really my grandmother's recipe. My bf likes it so much that he makes it himself and he was the one to nickname it "Grandma Itte's". The vinaigrette contains tarragon which gives it quite a bite; it's not meant to be a sweet vinaigrette. I usually make it in an empty 32 oz. vinegar bottle, but you can use a clean mayonnaise jar just as well. Just 1/4 cup of this will add zest to your homemade salads: potato, macaroni, coleslaw, even chicken salad. Or just enjoy it on your next garden salad!
