What's the national (food) dish in the UK?

It's very hard to define a national dish for all of the UK, as there are certain dishes that are either country 或者 region specific (such as haggis being favoured in Scotland, 或者 indian dishes in areas such as Leicester where there's a large asian population) so what's best is a country breakdown.

England: 鱼 & Chips (usually cod)
Scotland: Haggis
Wales: Laverbread (a strange seaweed thing)

A possible UK dish could be a Sunday Roast, pictured below.

Yorkshire puddings, mashed potato, roast beef, 卤, 肉汁 and plenty of vegetables are the main things in this dish. Very tasty.

as joe mentioned above there are a few place specific dishes but it's funny 你 should ask this as i was just watching a cooking competition 显示 and Jilly gooldon 说 the most 首页 cooked dish in Britain is actually shepard's pie, not sure if 你 have that in America but it's pretty must just 羊肉, 羔羊 mince often with carrots and onions and then mash pototoe on top. I did try and put up a 照片 the only trouble is i couldn't find any that looked appetizing.

anyway while chicken-tika masala is very 流行的 in britain and as is 鱼 and chips both originate from asia (although i think it was healthy grilled 鱼 and baked potato slices than the unhealthy fried stuff we now have lol)

so yes i would say Shepard's pie 或者 possibly as Joe pointed out a good Sunday roast, other typically english dishes would be things like toad in the hole (sausages in Yorkshire pudding) 或者 bangers and mash (sausages and mash potato)
I think we are pretty much a nation of people who 爱情 any thing with potatoes in lol

chiken tikka masala as well meat pies and 鱼 an chips

你 are correct dont know why but yo are correct bro
