Having a sunday roast which has a yorkshire pudding in it alongside a yorkshire pudding in god tier is a bit weird. I wouldn't say a yorkshire pudding is god tier alone, I wouldn't sit and eat them without say, gravy, or the other trimmings.

Cauli cheese I would put in top tier - but I'd also want to have it with a sunday roast.

Pie mash and liquor should be its own concept, and regular pie and mash (e.g., steak and ale) should be in a higher tier by itself, served with gravy

A good scotch egg (like, freshly made) should be in top tier tbh. A super market one can go in low tier though.

Haggis is definitely top tier - can actually go in god tier alongside fish and chips, it's my usual order when I go to a Scottish chippy. (Spicy haggis supper, salt and sauce - preferably going half and half with someone who got fish)

Can't say I massively disagree with the rest.
