Here’s a link to a site that gives a nice overview of the bacon family (and I’m not talking about Kevin and Michael):
http://www.foodsubs.com/MeatcureBacon.html
Bacon products that are defined (with photos!) include American bacon, bacon bits, Canadian bacon, fatback, gypsy bacon, Irish bacon, pancetta, salt pork, vegetarian bacon and turkey bacon.
This information could prevent you from committing a bacon faux pas.
