Yesterday I tried to cook these chili rellenos from Trader Joe's. They come frozen and I followed the package directions and had them covered with foil and baked in the oven for about 30 minutes. When I took them out, the top still felt frozen. I threw them in the microwave for 2 minutes thinking that would do the trick and when I took them out they were still frozen on top. So I put them back in for another minute. Took them out -- the top still felt frozen. Okay, what kind of food, or any earthly substance for that matter, still feels frozen after all this heating? I tried to scrape the top frozen part off the top and it was like a layer of frosty sponge. The relleno thing underneath looked hard and yellow so I ended up throwing the whole thing in the trash. It scared me.
