Andrew Rea is the host of "Binging with Babish" and "Basics with Babish" — two excellent shows on his YouTube cooking channel.
"Binging with Babish" focuses on adapting foods from pop culture, which sounds fluffy but is surprisingly dense with useful cooking information. His take on Spaghetti Carbonara from "Master of None," for instance, demonstrates how to make pasta from scratch, among many other useful techniques.
"Basics with Babish," however, is even better for pre-Thanksgiving prep. It's the kind of basics-focused cooking show that reinforces crucial foundational aspects of cooking that you'll need for the upcoming holiday. Ever wondered why some gravies are better than others? His episode on sauces will answer your questions. As we all know, Thanksgiving is really about the gravy.
