I remember seeing my Mom molding patties for these when I was just a tyke. I asked her what she was making and she said “Bear Steaks”. To this day that’s what I think of when I see them anywhere. These are from Ree Drummond’s recipe from her show The Pioneer Woman.
I looked at Wikipedia to see what they had, hoping to find out how it came to be named named as it is. It seems to have been invented by Dr. J. H. Salisbury (1823–1905).
