You are not alone HTC, Sheet happens!!
Just a couple of weekends ago I wanted to make a south-tirolian Carrot Cake, and somehow it became a disaster and I still don't know where I went wrong, I mixed the ingredients and baked in the oven as the instruction said (or I believe I did) yet it came out as a horrible hash, outside sticking to the silicon form (which should never happen), inside still slimy goo.
Then I wanted to bake a multi-grain bread filled with sunflower seeds, sesame seeds, linseeds etc. just like the ones we enjoyed in the south alps this summer... now this thing came out all dense and like a brick, if I toasted it it could be somewhat edible but... I hate it when a bread turns out like this... I suspect when I added the sunflowerseeds they were too cold, they came from the freezer and probably I didn't "defrost" them enough.
Anyway it was a quite demoralizing double disaster, Cris had to take over the kitchen for a day or two while I was swearing I would never touch anything in the kitchen from now on, but thankfully, things are back to normal, my risotto and Brussell Sprouts & Mushrooms in the skillet with cheese and bechamelle were very tasty last night!
