Mmmm, what a great thread to return to after an absence!

I had a bunch of things to add, most of which I've forgotten.

1. What USns call jelly doughnuts I called a jam-buster. (In general I never use the word jelly, because my mother continually pointed out we rarely eat jelly, but often eat jam. Therefore my sandwiches are peanut butter and jam sandwiches. But I digress.) They don't seem to know the word jam-buster in Newfoundland so I often have trouble ordering one at Tim Horton's, I just don't know what the heck they're called here!

small batches of dough left over from making bread

2. A great Newfoundland word along the lines of the original concept of doughnut is touton, deep-fried bits of bread dough, usually eaten with butter and molasses. (Touton rhymes with floutin', not crouton, with a "Canadian-raised" ou sound.)
3. In the west, we were served similar things known as (a) elephant ears, or (b) beaver tails, and eaten with jam, icing sugar, syrup.... These were flatter and crispier than doughnuts but are definitely from the same genus.
