I saw these Buddha's Hand fruit at Whole Foods today. I had never seen them before. I looked them up and they are an Asian type of lemon and they are also referred to as fingered citron. Buddha's Hand fruit is more edible than a traditional lemon and the pith isn't as sour. Apparently you can slice up the fingers and sautee them or use them in salad.
Have you ever cooked with a Buddha's Hand?
