Freshly butchered venison should be properly aged at least 12 hours before canning.
Prepare canning jars by heating jars, and keeping them warm until ready to fill.
FOR HOT PACK: Remove excess fat, sinew, and silver skin. I recommend grinding using the largest grinding plate. Ground venison cooks down quite fine.
Cook ground venison at least two-thirds of the way to doneness (rare).
Strain any excess fat and rinse with hot water.
Prepare your desired liquid by warming it on the stove. Use tomato juice, water, or broth.
Fill the jar with ground venison. Leave 1" headspace.
Add desired liquid, leaving 1" headspace.
Add salt if desired. 1 tsp for a quart, 1/2 tsp for pints.
Remove air bubbles.
Clean the rim of the jar with a paper towel moistened with white vinegar.
Add a NEW metal canning lid.
Secure finger tight using a metal ring.
Processing time and pressure depend on your altitude. See Notes below.
