unholy frijoles

it's really hard to know for sure whether the refried bean is your best friend or your worst enemy. one day it's a marvelous uberfood: tasty, easy to eat, filling, packed with protein-- but then another--[queue dramatic music] duhn duhn duhn-- it's got you in its evil clutches, up with middle-of-the-night throes of zinging pain accompanied by unsavory emissions.

such flip-flopping behavior is just no good in a relied-upon food.

and a dilemma-- of course I'm going to throw out the rest of that can of beans-- but what about the three others I got at the same time? are their contents part of the same tainted batch? and I constitutionally loathe waste. so do I risk another (or potentially *three*) excruciating night(s) up in the wee hours? I suppose I could give the unopened and suspect cans to the food bank, but that seems like a rather shabby trick-- potentially! because who knows! friend or foe?
