Several day ago, a friend of Jan’s (Jennifer Anderson) gave her three yuzu to pass on to me. Yuzu’s flavor is describes as a cross between a grapefruit and a mandarin orange. They are the size of small oranges, but not particularly juicy—the three yuzu produced ⅓ of a cup of juice. This sour fruit juice is the key ingredient in authentic Japanese ponzu sauce.
