Can anyone suggest a cookbook/website that does a good job of laying down the basics of cooking?

So my guy wants to learn how to cook (and yes, we’re looking into cooking classes). He feels like he’s lived thirtysomething years without learning how to do the basic fundamentals of cooking, and wants to change that. He can make pasta, boil or steam veggies, and BBQ, but wants to learn more skills. I know some skills, but I’d like to improve. We’re looking for a site or book that teaches more about how to cook and also has recipes, more than just a recipe book. Just wondering if anyone has a favorite from personal experience. Thanks!
