Most Sherry Vinaigrette recipes call for sherry vinegar as the base for the dressing — not mine! I use actual sherry and combine it with white wine vinegar. I think if you’re making sherry vinaigrette, use sherry!! Plus, I use sherry in lots of recipes so I always have a decent bottle in the frig. If you have sherry vinegar and not sherry, you can use the vinegar as a substitute. But try it with sherry — you’ll be pleasantly surprised!!
Begin by combining the sherry and vinegar. Next, add the garlic, mustard, scallions, thyme, parsley, salt and pepper. Slowly blend in the olive oil.
