Pre-seasoned Cast Iron Pans

Kashrut
1

I purchased new cast iron pans from The Field Company. Similar to most (if not all) other cast iron pans, they come pre-seasoned. I asked the company what they use to season the pans and they disclosed that they use two coats of “La Tourangelle” grapeseed oil and a proprietary blend of beeswax (from Bulk Apothecary) and mineral oil (source is undisclosed). Is it OK to use the pan without kashering? I assume if its OK its also OK for Pesach? If not, what is necessary to kasher the pans? Thank you!

Easy to kasher it.
Put it on the fire without anything in it and wait a bit till it gets hot enough. Throw in a few drops of water and watch them boil out and it’s kosher.
I’m assuming preseasoned still doesn’t really add flavor that would make it non-kosher, but unless they give us specifics in writing, I’d be reluctant to rely on that.

Does this apply to koshering a year round pan to use on pesach as well?

Yes

I’m confused. The oil used to season a Lodge Cast Iron pan is kosher soy oil. It seems the oil is recycled after pans are seasoned and reused for the next “batch” of pans as part of the manufacturing process and therefore is not certified kosher. Thank you.

Here is what Google Ai gives me: AI Overview

Lodge cast iron cookware comes pre-seasoned with a soy-based vegetable oil that is Kosher-certified

. While the oil itself is certified, the manufacturing process for the seasoning application is not under formal Kashrus supervision. The seasoning is plant-based, natural, and free from animal fat.

For strict religious observance, some users choose to kasher (clean/treat) new cast iron, which can be done via a self-cleaning oven cycle followed by re-seasoning, as discussed in. The pre-seasoning on Lodge pans is designed to be ready to use immediately.

I don’t understand what your point is.

Some cast iron pans are seasoned with non kosher products. According to your AI, Lodge only uses soy oil. But what about all the other brands?

I was mainly concerned with Lodge as I have a new Lodge pan and want to do the right thing.
