My friends Linda and Kelly Hayes are big meatball fans. (Well, let’s face it: They’re equal-opportunity foodies.) They’re also great cooks. One time I was enjoying yet another delicious meal at their house, and Linda suggested I do a riff on spaghetti and meatballs for this book. What a great idea, I thought. This dish is unquestionably hearty, and yes, it takes a bit longer than some other recipes in this book, but I promise you, the results are totally worth it. Oh, and the burrata (cream-filled mozzarella) on top? Amazing. If you can’t find it, then do yourself a favor and get the best-quality fresh mozzarella you can find.
