Yeah, Food Network is very rarely any more about teaching you anything cooking-related. I still tend to watch Chopped and Beat Bobby Flay, which are usually on as background noise, and then watch Worst Cooks In America, because that's as compelling as a train wreck. It's horrific, but you just can't look away.
As far as cooking instruction, Michael Symon has a decent show on Food Network right now, and the wife likes Trisha and the queen [Ina Garten]. But I don't really think of any of those as "instruction" any more, it's more that they're giving recipe ideas. We see something they've made and if it looks like something we'd want to do, look up the recipe.
I still say the best competition cooking show is Top Chef, and it's not close.
For cooking "instruction", you're better off on YouTube than any TV channel...
