I would like to also try that iron skillet Eliza mentioned, esp b/c I once had to take iron pills. But I honestly can't imagine an iron skillet by soaking clean after just 15 minutes. I can soak my steel skillet for 15 hours and it's not easy to clean!
Do you just apply salt w/o water??? this is intriguing.
I may buy a Telfon anyways, and use it at very low heat. For when I'm lazy. (which is more often than I'd like to admit)
