The NY Times has a video of Melissa Clark making vinaigrettes. I am with her all the way until she gets to the part where she dresses the salad right in the bowl. I was always taught to dress a salad the following way: rub the bowl with a piece of crushed garlic, add the greens, toss throughly with olive oil, add salt, and finally, the acid, whether vinegar or lemon juice or whatever. In particular, I was taught to never put salt on the greens until they had throughly been coated with oil lest the salt wilt the greens. Melissa Clark has you toss the lettuce with vinegar first, add the salt and then add the oil. To me, this is a prescription for limp salad.
