Here`s a beef heart recipe that i came across a while back.
2 lbs. of cleaned beef heart
1 1/2 lbs. of fresh cod, scrod, or peeled table shrimp.
4 egg yolks (no whites)
20 prenatal vitamins
1 cup of wheat germ
1- 2.75 ounce bottle of Tetra "Color Bits" (from your pet store)
1 cup of ground up freeze-dried krill or plankton (from your pet store)
1/4 teaspoon of spirulina powder (from your health food store)
2 packs of Knox Gelatin
Have flake food on hand if the mixture is the wrong consistency.
Clean all fat, veins, and sinew from the beef heart, and cube into one-inch squares.
Puree beef heart and fish separately in a food processor. Mix the beef heart, fish and egg yolks together.
In a blender, grind up all of the dry ingredients to powder and add to the beef heart, fish and egg yolks
and mix together. In the blender, blend the gelatin with one cup of cold water on high speed until it
thickens (about 3-5 minutes), and immediately mix into the beef heart mix. If the mixture is too runny,
add flake food until it is a doughy consistency. If it is too dry, then add water. Freeze prepared beef
heart mix flat in small zip-lock bags about a half-inch thick
