Well, here's a silly little report.
Threw out a large container of "whipped topping" another sewing group member insisted that I bring home from last weekend's retreat. She had asked several people (including me) to bring some. I rarely buy the stuff, but took in a good name brand and it was all used up.
This tub she gave me is a generic brand. I tried some of it on a graham cracker last night -- and all I could taste was chemicals.
I hate throwing food in the trash, but that stuff was no good to anyone. Not even worth saving the plastic container.
