I had just arrived in Canada 2-3 years before this or so and was at my first pot luck at a friend's house. One of the participants was going to be bringing pierogies, which had me excited, because my mom used to make pierogies all the time, but hadn't made any since we moved to Canada.. and now that I think about it, I don't think she made all that many in Germany either..
Meat pierogies were a childhood delicacy.. That's how my mom made them and that's how all pierogies I've ever eaten or heard of arrived: They were either stuffed with pork and spices, mushrooms & cabbage, or strawberries. The mushroom ones were reserved mainly for Christmas and the strawberry ones were a dessert sort of thing, which I did not enjoy at all. Meat was where it was at! If it wasn't Christmas and we weren't eating dessert, there was nothing to expect inside that pierog but meat.
So I'm sitting there, all excited, and I bite into one of these pierogies, expecting sweet sweet pork.. but.. the texture was all wrong! And the taste wasn't there! I spit out what I had in my mouth out and started prodding the pierogies with my fork.. They seemed to.. have some sort of a MASHED POTATO LIKE MIXTURE INSIDE?? WHAT THE HEL!l?$!?$ WHO DARES PLAY SUCH GAMES!?
So I of course started questioning what the F is in the pierogies.. "Uhh.. potato and cheddar".. "WHO THE F PUTS POTATOES IN PIEROGIES!?!? WHAT IS WRONG WITH YOU!?!?!" Seriously, was this person crazy? Mashed potatoes INSIDE OF PIEROGIES? This was unheard of. This was madness. I asked if it was a joke of some sort and quietly hoped that real pierogies were being hidden from me and that this was all a big practical joke. But nope
I calmed down, but my dreams were crushed. I was expecting that sweet sweet childhood amazingness when I bit into that pierog.. But no, instead I was treated with a texture that was completely wrong and a taste that was way off as well. It was wrong. It was 100% WRONG. It was disguisting. It was like picking up what you thought was a glass of water, and downing a bunch of vodka.. I have nothing against vodka, but when you want water, you want water.
I've gotten used to these weird pierogies and now love them. I still prefer meat pierogies, because they are far superior, but cheese pierogies are enjoyable for me now too.
I used to be a picky eater but am not really anymore, I'll sort of dive right in and try new stuff. So I can't really think of any other story that might qualify as "worst food experience". The first potato pierogi experience was just truamatizing, I can't think of any other story to share.
