Here are a few great channels from my Youtube subscriptions!
Tasting History with Max Miller hits a perfect cross-section of my interest in cooking and my interest in history. Max goes through a historical recipe each episode and pauses part of the way through to explain the history of the dish.
Minute Food has lots of short (sometimes under a minute!) videos about the science behind cooking.
Chinese Cooking Demystified is a husband-and-wife duo living in China that goes over traditional Chinese recipes, I especially like how in the voice-over they frequently list substitutions for ingredients that may be difficult to find outside of China.
Atomic Shrimp does far more than just cooking, but the cooking videos on his channel always give a neat insight into the everyday meals an older British IT Specialist makes.
Good job, Tails! Now fly me to that platform over there...
