That was my understanding. Just checking.
My mother never bought anything but lamb's liver (calves' liver was far too expensive) when I was a kid - and she made liver and onions regularly.
I was very surprised when I moved to China and ate lunch one day in a small three table restaurant near work. I found 'liver and onions' on their menu. Of course, I ordered it. It was absolutely delicious and only slightly different from my mother's despite the Chinese influences. I asked and found it was pig's liver.
Now I regularly and happily eat pig's liver - it and chicken being the only ones I can get. No cows or sheep round these parts. Oh. I do get anonymous fish livers, too.
This picture was taken years ago in that very restaurant on a return visit (one of many - it became my work canteen!)
