This french vinaigrette dressing is traditionally whisked together in the bottom of a large salad bowl. After it's made, lettuce and any other ingredients are added to the bowl and gently tossed to completely coat the greens, while leaving any excess dressing at the bottom of the bowl. It's a fabulous technique that leads to perfectly dressing salads, but whipping up a double, triple, or quadruple batch in a small jar to use over the course of a few days is a nice option, too.
