I am not Sicilian. I have made thick crust, fried pizza by liberally coating the CI pan with butter, and WEVOO, thin crust with just a coating of oil in a 500' oven, dep dish , and stuff crust pizzas. I have also made all of these over screaming hot lump charcoal on the Webber Kettle, with the lid on. All of them came out great. Everyone has their preferences. ability to create great pizza is a function of knowledge, not ethnic background. /You don't have to be a cowboy to make great chili. You don't have to be from Naples to make great Neapolitan pizza. You don't have to be from main to cook great lobster. You do need to do the research, understand the properties of your heat source, and cooking tools, understand flavor components such as herbs, spices, smoke, slight charring, and textures, and how to obtain them. You need to understand how to balance flavors, and in the case of pizza, understand the difference between well topped, and to much on top (keeps the crust from cooking all the wat through).
I tend to take exception when anyone says - I'm such and such ethnicity, so I know. I can pretty much make any kind of food, from anywhere in the world, that I desire to make. If I'm unfamiliar with a recipe, then I can ask those who are familiar with it, or do the required research. Please don't throw ethnic background at me, as I'm sure there are French who can't make a good cassoulet, and Italians who can't make a proper Bolognaise, etc.
Sir-Loin-of-Beef, I know you to be a very good cook. I'm not trying to insult you, or chastise you. Your knowledge, and perhaps the things learned from family, are what sets your cooking apart. That's all I'm saying. We are all born equal, knowing nothing. We all learn everything, except for the auto functions of our bodies. Jut because I have a lot of Native American in me doesn't mean I know how to harvest, and cook cattails.
