This is a Buddha's hand, also known as Citrus medicavar.sarcodactylis. I stumbled on it while at my local Jewel's store. Rob the nice produce manager (pictured above) told me they come from Asia and torn off a tip of one of it's fingers for a couple of shoppers to experience. The fragrance was truly amazing. While it doesn't have the juice or pulp you'd expect from a lemon it can be used for drinks, juicing, and to make candy. Can't wait to try one soon.
