OK. Sticky toffee pudding is a heavy spongy cake made with dates, smothered in a hot toffee sauce. Gorgeous, but very rich.
Cream soda is a soft drink that tastes really creamy. Very sweet and sickly.
Clotted cream is the thickest cream imaginable, and only ever seems to be served with fruit scones.
Potted shrimp are cooked shrimp in a little pot or ramekin, topped with a very thick layer (normally around a centimeter - very thick!) of butter. Sounds repulsive, but is gorgeous on hot toast.
Scouse is a thick stew made with cheap beef or lamb, potatoes and veggies, cooked for hours until everything falls apart.
Curly wurlies are toffee bars covered in chocolate.
Oatcakes are thin pancake-type wraps made with oats. Disgusting cold, they are nice only when heated and served with a nice topping (my favourite being cheese and bacon).
Can't help with the Maltese dishes I'm afraid!
