Hello everyone! I'm opening my first food business, a pancake(crepe) street food cart. I'm living in Hanoi, Vietnam and here they don't have access to a good European brands for professional crepe makers, but only local Chinese analogs, which could be good. But the problem is, I have no idea what is material of griddle made of, since manufacturer doesn't mention it. I want to have non-coated cast iron, since I've read it would be the best for intensive using, and it's not too pricey. I went to the shop, and right now, they have only two models(gas and electric), which they claim are both cast iron and both coated, but for me they look different. If you have knowledge in that, can you take a look on this pictures, and tell me what is what. BTW, does this scratches(pic.3) could affect the process of cooking? Thank you in advance!
