I have my grandmother’s cast Dutch oven. It has so much seasoning to it that absolutely nothing sticks to it. It’s the best cooking utensil I own.
Oh, forgot about the cast iron dutch oven no one has bothered to take out of the box all these many years.
I do use grandma’s cast iron skillet daily. Also, have grandpa’s little cast iron skillet he used for his pre-dawn breakfasts. Never understood people today worrying so over the care and feeding of delicate cast iron.
