I learned a lot from watching the original Japanese Iron Chef. You’re not learning recipes of any sort. What I learned were techniques and that it’s okay to experiment and be creative in the kitchen. For day to day meals, it works pretty well when trying to come up with meal ideas based on what’s on sale at the grocery store. If I want to try making something specific, that’s when I search for recipes.
The comments on that video made me wonder what the astroturf was going on, then I saw what channel posted the video.
