I never understood fans of cast iron. Its like still using candles for light, sure it gives a warming light, but electricity is cheaper, safer, and quicker to use for light. Same for pans, stainless steel have exactly the same use as cast iron without any of the inconvenience. Sure heating behavior is different, but who cares, you can get to the same results with stainless steel with a bit of experience… If you really want that “hipster cooking” feeling, just use copper, sure its way more expensive and you need to be extra careful, but its still better than to try using cast iron which is a real pain in the ass to use, making cooking twice as long as it should be… And for Teflon… it’s shit, weak as hell and will give you cancer. Aluminum is shit too, still better than teflon and at least its the cheapest.
Normans were in France since at least 3 generation before the britain invasion. So they were clearly french culturally and they were fully merged with the locals genettically. Also the invading army had troops from nearby french region like Brittany or Anjou.
