My grandma used to make what we called oatmeal sausage. It is a bit different but very good. I've only made it a couple of times. I hate peeling beef tongues.

Oatmeal Sausage by Granny B
4# Beef tongues
6# pork shoulder (Can use all pork shoulder if it has skin on) Dad’s recipe also has 4 lbs pork hocks
1 pkg. pearl barley
1 pkg. long cooking oatmeal (small)
3 Tbs Thyme
Cook and grind meat mid coarse-cook barley and oats. Let everything cool.
Add mix. Salt everything according to directions on box and then 1 tsp pepper and salt to taste. Cook patties in butter until crisp on each side.
Saved broth that meat was cooked in to cook the oatmeal in.
