Next time you decide to whip up a batch of hummingbird food for your non-existent hummingbirds, do not - I repeat - do not talk to your sister on the phone at the same time. Because, as you'll recall, the last time this happened, you were so engrossed in conversation that you forgot about the hummingbird food. . . until you got a whiff of the stench which nearly smoked the neighbors out of their house and then puffed up like a gigantic marshmallow that's been caught on fire becoming completely black and crusty in the now-ruined pan.
If you decide to do this again, kindly remember your friend Barbara's tip: microwave the sugar water for a minute and a half or so - or until the sugar is dissolved.
