We went to the local produce stand and bought 2 big boxes of sweet potatoes yesterday. One was a box of nice pretty medium sized potatoes for $15. The other was a box of "culls" for $5. When I got home I went through the culls box. Peeled, washed, and canned 13 quarts.
I'd never done this before so I looked on the internet and tried 2 different ways.
The first I just cut up the raw potatoes into chunks and placed them in the jar. Added 1/2 tsp of kosher salt and then filled with boiling water. Put into the pressure canner at 11lbs for 90 minutes....yes it was a long one! This is also how I can regular potatoes.
The second I cut them up in chunks and boiled them for about 5 minutes. Then placed into the jars with 1/2 tsp salt & 1 tsp lemon juice. Filled with boiling water & again pressure canned at 11lbs for 90 minutes.
Here were the results of my canning. Anyone want to know what one looks pretty & what one looks blurry?
The uncooked, salt & water only are to your left. The cooked ones with the lemon juice all look blurry. Of course they are perfectly fine but I think I'll stick with method #1 when I do it again.
So I paid $5 for the box. Ended up with 13 qts. and enough to make about 4 more. So lets say 17 qts. I had the salt & lemon juice (which I won't use again) So let's add the salt in to the price...So I'll be generous and say .30 for that. I already had the jars & seals but you always need new seals so let's add $1.50 for those. I really don't know how much propane it took to cook them so let's add in one more $1. Total would be $7.80.
So per jar would come to: .46 per jar. Not bad when last I checked Wal-Mart was selling their cans for $2.50 each!
