my signature vinaigrette

Umeboshi is a small Japanese plum traditionally used to make a super-salty, bright red vinegar. Antiseptic, fortifying and mineralizing, umeboshi contains more than 17 health-boosting substances. And it’s the key ingredient in my best-known vinaigrette, which is dead simple, by the way. Just be careful: there are several companies that make this vinegar. I prefer the Koyo brand.
