Cooking is a hobby of mine, and as a result I really enjoy watching food related YouTube channels. Some of the ones I like are
Alex French Guy Cooking - A fun channel of a creative french amateur cook. I like this channel because I have similar taste in food to him (check out his instant ramen series!), but his solutions to problems in the kitchen are seriously creative. To give an example, he builds a dough sheeter in his croissant series in order to get the perfect thickness of dough, and he makes a makeshift dehydrator in the ramen series. Stuff I would never do in the kitchen, but it's fun to watch.
Bon Appetit - I totally did not expect Bon Appetit to have such a well put together web presence (for some reason I considered them an old fashioned publication). In any case, check out the "It's Alive with Brad" series. It starts out as a series about all things related to fermentation (beer, hot sauce, kombucha, sourdough, etc), but expands a bit in scope.
Binging with Babish - Perhaps the most well known of recent food related YouTubers, Babish recreates meals from movies and TV. He also has a nice series on cooking tutorials. I don't watch him as much as I used to, but he's still a lot of fun.
Townsends - A bit different than the rest, and not exlusively food related. Townsends is a historical enthusiast focusing on the colonial era, and he has a lot of videos recreating recipes and techniques from the time period.
Forgot to include
- Jun's Kitchen - Some seriously therapeutic cooking videos featuring sushi and cats.
