1. Bring 4 quarts water to boil in large pot. Add garlic to water and cook for 1 minute. Using slotted spoon, transfer garlic to bowl and rinse under cold water to stop cooking. Peel and mince garlic.

2. Add ravioli and 1 tablespoon salt to boiling water and cook, stirring often, until al dente. Reserve 1/2 cup cooking water, then drain ravioli and return to pot.

4. Add 1 cup pesto to ravioli and gently toss to combine, adding 1 tablespoon cooking water at a time, as needed, to adjust consistency. Serve, passing remaining pesto separately. Sage, Walnut, and Browned Butter Pesto for cheese ravioli
