Sorry to crap on your recommendation but there are a million other cast iron woks that are more suitable for Chinese cuisine than that lodge cast iron wok.
It's the first Cast iron one that pulled up in search.
Reason is that is it way too heavy and the walls are too thick. You cant pick it up and flip food around with this.
It's not THAT heavy, and if you can't pick it up and flip food around in it......grow some balls? Or hit up gym?
Not sure what to tell you....
Due to the thermal mass, this wok is too slow to heat up and cool down. It lacks the heat dynamic that Chinese made woks have. However, this would make a great deep frying vessel for its ability to retain heat.
Heating up and cooling down plays VERY little role in actually cooking the food. We are talking HOME usage.
OP doesn't work at a food place where things need to happen fast. I'm SURE waiting extra 2-3 min for it to warm up completely is no big deal.
Besides, WOKs are used over high heat, even thick cast iron heats up VERY quick in high heat.
You could try to cook with this wok but you are going to have to greatly modify your cooking technique if you intend to follow guidelines/recipes written for a traditional Chinese thin walled wok.
If you are anal about this sort of thing, techniques.....guidelines etc.......I guess.
When it comes to cooking though, TO ME, it's all about creating and modifying recipies and techniques to your own liking......for YOURSELF.
I don't like to live my life by the book, but I will use the knowledge from the book and adjust them to fit me proper.
OP is NOT a master chef, he will do JUSt fine with the wok I recommended.
Heck I've used my 15" Cast iron SKILLET (not even a wok).....on med/low heat.......to cook PLENTY of Chinese dishes and they all came out great.
