Never ever ever ever ever leave the kitchen with a pot simmering on the stove. I do not remember pots, any more than I remember that I'm out of toilet paper. (Actually, after a decade or two, I have myself trained to remember when I get low. This may be because I now buy only one brand that's available at only one neighbourhood store, the one I don't regularly shop at. So when I enter Loblaws I always think 'Do I need tp? do I need batteries? do I need crumpets?'- those being the usual reason I'm at Loblaws in the first place.)
However, the baking soda and detergent trick works perfectly, so I still have a pan.
