Direct, high heat works well for quick-cooking foods, like hot dogs, burgers, and chicken breast, but ribs don’t fare quite as well when cooked in the same conditions. High temperatures and direct heat can easily lead to uneven cooking, and can dry the ribs out.
Follow this tip: If you’re grilling ribs (versus oven-cooking), placement on the grates is important. While a few minutes over a high flame can leave a nice finishing char, the majority of cooking should happen over low or indirect heat. This guarantees more even cooking, and will help lead to more tender ribs.
