Dont bother with 'pre-seasoned' at all. It's machine grease you have to
eradicate before use to start with.

Just cook lots of fatty stuff for a week or so in the pan, wiping clean with
a cloth. First cure is in the oven coated with a thin layer of crisco (250
or less, 3 hours) then cook in it.

Do not wash in water if you can avoid it for about 12 uses and only with
care after (and use just water, not soapy water). This is 'natures teflon'.
