Back bacon readily available in any good grocery or supermarket in America; usually called Canadian Bacon. Generally sold unsliced; one cuts to the thickness desired.

In the sandwich I was talking about I use top quality streaky bacon, thick-sliced. Too crisp and all the great, lovely fatty taste disappears. Price varies according to quality; the best is at least twice the price of the ordinary.

Canadian (back) bacon is expensive relative to streaky; usually we serve it with eggs, sliced thick, lightly cooked and never dried out.
