Beef stock = beef stock
Bell pepper = bell pepper, or just pepper.
Clams = clams
Corned beef = corned beef
Crayfish = crayfish
English muffins = sometimes called white muffins, other times called "oven-bottom muffins"
Gingerbread = gingerbread
Hot dogs = hot dogs, or "American hot dogs"
Lamb chop = lamb chop
Lemonade = cloudy lemonade (or, at Sainsbury's, "Sicilian lemonade")
Lima beans = no UK equivalent. Broad beans are NOT the same!
Pudding = not custard
Saltines = a US brand name. For nausea, cream crackers are the closest equivalent I've found.
Shrimp = JUMBO KING GIGUNDO prawns, if you're trying to find medium-sized 26-30 shrimp.

Sprite = Sprite
String bean = dwarf beans. Runner beans are something entirely different. I prefer "stringless" beans, which are essentially pole beans.
Sweet butter = Unsalted butter (but it's called the same thing in the US!)
Tater Tots = a US brand name.
Tenderloin steak = tenderloin steak, or "fillet" steak
Whipped cream = whipped cream, if referring to ready-made cream in an aerosol can, or "whipping cream" if referring to the cream itself, in a pot.
Many of the "UK" names on your list are regional variations, not UK equivalents. I'm sure SOMEONE in the UK calls aerosol whipped cream "squirty cream", for example, but it's sold in the stores as "whipped cream."
