She has made several chocolate cakes that everyone has liked and nobody has known has beans in it until told.
Having a culinary background, the mere thought of using beans in a cake sends chills up my spine, especially if you ever had a serious case of food poisoning, you'll know what I mean. I'm not disputing that beans (legumes) are good for you, and make a good prep item for long term food storage.
But to use Beans in a cake scares the crap outta me for the following reasons, once beans have been hydrated, or cooked, they will start to form dangerous bacteria after 2 hrs at room temps, or anything below 140 degrees. even if you reheat it the next day, that bacteria will die off and leave behind deadly toxins that will make you gravely ill.
if used in a cake and left to sit on the counter over night is a recipe for food poisoning disaster. Beans spoil extremely fast once they are cooked, or re-hydrated. and are one of those items you never want to put in the frig for the next day.
even in the dept of corrections, the most common illness with inmates was due to food poisoning from you guessed it....Beans.
