One of my husbands friends have been over for dinner twice. First time I made fried chicken.... he won’t eat meat off the bone. 
. The next time I made baked ziti. He won’t eat minced beef.
We’ve not invited them again. 
I appreciate the f*ck out of my closest friend I've made here because her and her fiance love American food and don't constantly look at the calories in it or the sugar content in the puddings etc. etc. and they will pretty much try ANYTHING. She gets invited over for the thanksgiving feasts and she gets the baked goods brought to her. Everybody else can go pound sand
I make my English stepdaughter try EVERYTHING for that exact reason. She's 10 years old. I would ask her if she liked something and she would say "no." So then I'd ask if she'd ever eaten that thing before and she'd say "no." I told her she's not allowed to say she doesn't like something if she's never tasted it. Thankfully, she listens to me and trusts me. With that, I have now gotten her to try foods she would have run away from in the past. And she's finding that she likes more foods than she thought she would.
Two Christmases ago, I offered to bring some of my famous homemade baked mac n cheese to dinner and my brother-in-law wasn't having any of that. He basically said he didn't want anything weird at his traditional Christmas dinner. Hey, no prob! Less work for me. But it's also not weird and it is MY tradition. My husband and stepdaughter think my mac n cheese is to die for. So, I cooked some at home the day after Christmas and we all gorged ourselves. My B-I-L and his family missed out big time. People are funny with their ways.
All kids (or most kids at least) are fussy. I expect that and it's great that you're actually pushing her to try these things she's not tried but is convinced she doesn't like
I just don't expect this from grown-a** adults! It's almost like they've NEVER been pushed to try anything outside blandness their whole life! (not all Brits, obviously! just the volume I mentioned). It makes me SOOO happy when I meet Brits that love a good Mexican or BBQ or pudding more than I can even say!
I totally can see my in-laws making comments about things that are delicious just because they think it's "weird". Like I had to listen to my BIL talk about how sugary and high in calories s'mores were...like STFU SIMON! LIVE A LITTLE! I could get hit by a bus tomorrow and my calorie count wouldn't mean a thing but at least I died saying I ate something tasty!
I read that 70% of British people have never eaten an olive.
I've bagged me one in the 30% LOL He honestly buys JARS of olives and just eats them throughout the week. I can't stand the smell of some of them. UGH.
