Probably reitterating what's already been said but wanted to add my 2p-
I <3 pub food. Bangers and mash, toad in the hole, fish and chips. Uh, it's so bad, but oooohhh so good. (Yes, I had fish and chips in the US but it's totally not the same- especially not the same as chip shops.)
I <3 curry. And I never had that in the US.
Other things I've picked up since being here....putting spread on sandwiches... like spread on a sandwich with salami. I don't know what it is, but it is nice.
I'm also seriously in love with piccalilli and English mustard (it's great when you're nose tingles because of it! hahaha). And Coronation Chicken.
Sunday roast dinners are alright. I do find it to be a bit too much food sometimes though. Although, I could proably eat an entire plate of roast parsnips!
I have to agree with the custard comments though. Having been through my first UK Christmas and eating all the puds... I definitely prefer American desserts to British. And I am really not a fan of warm custard. It's just weird.
Ok, I'm hungry.....
