I was thinking a bap, but hard to tell from the pic (is it a roll that you put sandwich fillings/meat into?)
Some other thoughts:
Bing cherries are specific cherries, not just black ones in general.
digestives and graham crackers are not the same thing exactly (graham refers to the type of flour used)
it's just "zucchini" not "small zucchini", unless of course, your zucchini is size-challenged
Demerera sugar is most definitely not the same as American brown sugar (which contains molasses)
Powdered milk is much more common that "dry milk" (though it says that on the package I suppose)
gingersnaps are chewy usually, gingernuts are definitely not
I've baked loads and have never heard someone instructing me to use a "leavening agent". "Baking powder" it is
Cream of Wheat is a specific brand of mush in the US/Canada, and is not made from semolina
not "cultured", but just "sour cream" (sounds like elitist sour cream, heh)
They gut fish in America too. Also whisk stuff, grill things (broil = old fashioned)
All the UK folks I know use "kitchen towels" not "kitchen paper"
Patty cases? Never heard that one before either. Neither "top and tail berries" Top and tail is what I do to Freya each day
Skillet is much less common in most places in the US than "frying pan" (I often here "fry pan" here)
I've never heard anyone on either side of the Atlantic
say "cauliflowerets". Florets is commonly used in the US
Some others:
pizza base = pizza crust
fatfree milk = skim milk
Oi, I'm sure I should know more. I spent the first three months here getting to know all the staff at Waitrose (supermarket) because I didn't know what things were called.
