Stracciatella with Celery and Herb Salad and Celery-Leaf Pesto

One of the principles of Italian cooking—and maybe this is true of all of European kitchens—is not to be wasteful. Italian cooks find a use for every edible component of each animal or vegetable they cook. In the Italian spirit, I use all parts of the celery in this dish. I slice the celery ribs for the salad, and I use the leaves, so often discarded, both in a salad the cheese is served on and to make a celery-leaf pesto that gets spooned onto the cheese. The result is a bright, flavorful, and textural salad that is equally pretty and unexpected. We peel celery using a vegetable peeler anytime we are serving it raw; it takes only a few seconds and the celery is so much more tender with the fibrous strings removed. The pesto recipe makes 3/4 cup, which is more than you will need for this recipe, but it’s difficult to make pesto in a smaller quantity. Spoon the leftovers over grilled chicken, fish, or vegetables; use in place of basil pesto to make a tomato and mozzarella salad; or simply double the salad and the stracciatella in this recipe to make eight salads. Since stracciatella is hard to find, feel free to substitute burrata in this dish. I normally like to use only the pale green leaves from the celery hearts, but since this dish requires so many celery leaves, I call for you to use the darker green leaves for the pesto, reserving the light green leaves for the salad. If you were inclined to buy even more celery, then use the light green leaves for both parts of this recipe—and use the excess celery ribs as inspiration to make Basic Chicken Stock (page 27), Soffritto (page 28), Lentils Castellucciano (page 264), or any of our other recipes that begin with sautéed diced celery.
