my parchment paper turned black...
i put in two loaves that i've made several times at the exact same temperature (and yes, i use an oven thermometer) on this very same roll of kirkland parchment paper. only this time during the short 20 minute bake, i started to smell something burning, not food, something a little bitter that was hurting my throat. i look in and the parchment paper is mostly black, not dark brown but black, and it's smoking.
i didn't feel good about eating bread that had been absorbing that smoke, so i turned off the oven and am letting it air out. opened all the windows, too - it smells of burned parchment paper a lot in here, and that's while the fan over the oven was running the entire time the oven was on!
my oven thermometer read 450, the same as last time, but it's not digital. could 1 or 2 degrees higher have caused the parchment paper to burn?
