This wonderful tarragon-flavored mayonnaise is a version of one of my favorites, Bearnaise sauce. It makes a fantastic egg or tuna salad, or use as a spread on a roast beef sandwich with fresh tomato. Try a dab on a grilled swordfish steak, or dress a tasty macaroni or seafood salad with it. The possibilities are endless - it livens up everything!
- Cook together minced onion, vinegar, wine, dill, and tarragon until only a little liquid remains.
- Cool slightly, then stir mixture and mustard into mayonnaise.
- Add salt and pepper to taste.
