The magic of this dish is the surprise of the Bing (or ground) cherries and the herby slices of mozzarella. Slice the tomatoes, big and small, in different ways for a more dramatic salad; cut some into wedges and some into slices. Husk or ground cherries look like cherry tomatoes but offer a welcome tart flavor almost like a burst of mango or passionfruit. If they are unavailable, add a pint of fresh cherries, halved and pitted, instead. While I know the mustard isn't entirely classic in this iconic salad, I love how its flavor links up with the fresh herbs and brings out the almost creamy note in the cheese.
