Gustare Oils and Vinegars. I recently learned that adding the bit of mustard helps bind the dressing together for a thicker consistency.
1 small garlic clove, minced
3 tbsp extra virgin olive oil (I like Chile EVOO!)
1 tbsp high quality balsamic vinegar
1 tsp fresh herbs, chopped...I used parsley
1 tsp mustard
salt & pepper to taste
I'll have to do another post on my salad technique, but most often, I'm using this with a spinach or arugula salad. I like the consistency one gets tossing the salad with the dressing in a big salad bowl, plus that avoids people heaping more dressing on than they need. But if you think you might not use all the salad at once, it's better to let people serve their own dressing.
