Lamb, mutton, anything like that. I can eat some lamb, if it's really young. I generally hate goat cheese, but some I like. I don't like the cheeses that overwhelm with ammonia, either.
I used to hate mashed potatoes & celery, but I've been getting potatoes and celery in my produce delivery so I've revisited mashed potatoes and eating celery raw. Celery is good raw with a dip, but I can't really eat it plain because it is bitter and numbs my tongue. I still don't like mashed potatoes a whole lot, but they can be pretty good when I make them myself. I make them without adding milk, just mashing up cooked potato with butter, or garlic so that helps. But the instant mashed potatoes that we had in school lunches, or my mom made--yuck. I used to try them after awhile, and even the smell made me ill.
I loathe chocolate covered strawberries. Something about wet chocolate--just seeing people eat those dripping things disgusts me. They can probably taste OK, but they usually don't. And if the strawberries are really good, I want them alone. The chocolate they are dipped in is usually not very good anyway.
Which reminds me, I hate bad chocolate. Like the Palmers brand with the hydrogenated oils. I tried some not long ago, and I had to spit it out. White chocolate can induce the same reaction.
I also hate black licorice flavored stuff, and tripe, but I've only had tripe once. It smelled like dog food.
I used to hate green peppers and beets, but now I like them well enough.
I'm not really picky, I can eat foods I hate, for the most part. I still try and eat lamb and goat cheese occasionally, that's how I have found out there are some of these I like. But Boca burgers, I cannot stand them. I used to really like them, and then a flip switched and I can't tolerate the taste at all. And that disgusting chocolate, I can't even swallow it. I don't know what it is. I think in part it must be texture, which is a big part of why I dislike mashed potatoes and chocolate covered strawberries.
