I don't have allergies, but there are things I hate that are very prevalent in Spanish cuisine, and my father kept trying to catch me out whenever he'd bother to cook a meal. As I grew up I discovered many foods I actually loved, just not the way my parents prepared them: pasta and rice being two of them.

I'm actually a pretty adventurous eater, much more so than my parents were: I love Japanese food, I love bibimbap, I've eaten and enjoyed a lot of weird types of meat (and one, duck, became my favorite), and I'm always more than happy to go to a restaurant and try something within my parameters of edible (so, no onion taste, no mound of onions on it, no mushy stuff, no bell peppers, no peas, etc). I won't always like it (e.g. labneh was meh for me, but in that same meal I found out I like beets) but I will give it a go.

My father was awful for more than this reason, but he literally died mad about it. And about other things. My life is so much better with him out of it.
