Filling the pressure canner

I am new to pressure canning but have started canning a few things. My question is do I have to fill the canner up? Can I just do say 2-3 jars?

Just curious as I wanted to can some beef from my freezer but didn't have enough to fill the canner. BTW it need to be cooked as its been in the freezer about 5-6 months.

Yes you can run a partially filled load. It is more efficient to have a full canner but, if you only have 4 jars full and you really need to get it processed, it is perfectly safe to do so.

You need to follow the same instructions as if you had a full load. Do not reduce the time or pressure.

Great Question.
