HOWTO season a cast-iron pan -- with SCIENCE

In this particular instance, this is good advice. If you try to pick up flaxseed oil any other way than the cold pressed stuff from a health food store (because who else would carry the stuff?), you’re probably going to end up with linseed oil, which usually means “boiled” linseed oil, which is solvent-extracted flax oil mixed with petroleum distillates and drying agents. Great for putting on wood, maybe for mixing with oil paints, but not for anything that’s going to be touching food.
