Why does the liver not give them diarrhea?
Because liver brownie recipes generally use a lot of oatmeal. Oatmeal holds the brownies together well, especially since they can go through a lot of abuse in a handler's pocket.
This is the recipe I've always used..it's just GROSS when you liquify the liver in a food processor or a blender.
1 Pound liver
1 Teaspoon Pureed Garlic (you can get this in the produce department of your grocery store)
1 Package LIPTON DRY SOUP MIX - either Onion, Onion-Mushroom, Beefy Onion (whatever)
3 Cups Oatmeal (any brand will do)
Puree liver in a blender or food processor. If you use a blender, LISTEN carefully because it can get wrapped around the blade and wreck the unit.
Add eggs and blend some more.
Add garlic. If your dog is a hard sell at baiting, add more.
Add LIPTON dry soup (or any comparable flavoured dry soup) and blend some more.
Find a BIG bowl. Dump liver mixture in bowl.
Slowly add the 3 cups of oatmeal (if you do this enough, you will stop measuring the oatmeal because you'll have a feel for it).
Grease a BIG cookie sheet (or whatever) and dump mixture on it. Spread it around. It's like the consistency of brownies, sort of. You can decide on the thickness of the brownie by how you spread it around. About 1 inch thick is right.
Cook at about 300* for one hour. CUT IMMEDIATELY, stick in plastic sealing bags - sprinkle with garlic salt, seal and freeze.
