Cast iron is expensive. Between the material itself and the late hype for this particular type of kitchenware, price are high.
I bought my first cast iron pot for €45. It’s a 4 litre, so not that big.
I recently bought in a promotion a skillet and grill for €40, as a promotion, but each piece should have cost of around €40/piece. Most won’t fork that much.
Right now, I’m thinking about a nice paella or mushroom ragu to really break in the skillet.
