No, this isn’t a cast iron thing. Using stainless pans, you can get nonstick effects that, in my experience, far outperform Teflon anyway. The process is called “spot seasoning.” I have cooked crispy, cheesy rice noodles with eggs with zero sticking.
I love my cast iron pans, but stainless is my daily go-to. Added bonus: use 100% copper wool to clean your stainless pan. The copper-coated wool at most grocery stores is problematic; you might get a few uses out of the coated garbage and then it starts shedding metal bits.
I went for a cheapish knife, like £20 or so each for a few knives. My thinking was I don’t want the 20 knives in a set for £19.99 that are probably made of stamped aluminium and hollow plastic handles, but by £20 you are getting something good without spending a silly amount of money.
As for the cast iron I won’t deliberately leave mine to rust, but happily use it over a fire and then just wipe off the worst of the soot/ash. But it’s black anyway so no one is going to notice spot buildup. Just remove anything that would easily brush off on other things.
I agree with your approach
I think knife sets are a bit of a con job because a good cook really just uses one or two. I’m looking at my knife block and I’m seeing 9 different knives in there, two of them get used. Two… The $5 el-cheapo chef knife and a $1 paring knife. I haven’t used the serrated bread knife in 10 years, because my chef knife is sharp enough to shave my beard
I’m also kind of exaggerating a bit on my prices. Yes I’ve paid $5 or 6 but I time the purchases to be right after Christmas when they’re on clearance. I’d say in “real money” and with recent inflation I’m using about a $35 CAD knife
I also find the pricing of them to be completely arbitrary. I have been gifted knives that should be extraordinarily high quality based on retail price… And found the handles/plugs were falling off, or they were degrading within weeks!
I don’t understand why we live in a world where someone can sell a $500 knife that in terms of manufacture and material cost, is almost indistinguishable from a no-frills budget one. And in many cases, conspicuously worse in every measurement!
