I have always wondered what a “rasher” of bacon was. I didn’t know if it was a single slice, a serving (2-3 slices) or a whole pan. Bacon was never referred to in these terms in the time and place where I grew up, so when I heard the term in popular culture or in cooking references (I love to read cookbooks) I really didn’t know what it meant.
A rasher of bacon (orig. English) is either a single slice of bacon or a serving (2-3 slices). Both definitions are commonly used in England and Ireland. The word is thought to come from an old word “rash” meaning slice. It makes sense to me!
So if I ever visit England or Ireland, I will probably not order a “rasher” of bacon- I’ll just say bring me lots!
