Mozzarella is a flavor sponge. It readily soaks up good stuff like extra virgin olive oil and garlic, so why not give it a little bath on Labor Day? Ciliegine, the cherry-size balls, are perfect for marinating. They’re bite sized, you can serve them whole so they don’t release whey, and it doesn’t take long to infuse them with seasonings. (Say chili-eh-GEE-neh.) I add dried oregano, parsley, Aleppo pepper and capers, but you do you. Taken to a potluck or at your own backyard barbecue, these juicy, garlicky one-bite wonders will vanish before the burgers are done.
