Heres a recipe i do every spring with suckers.
For one pint jars, add:
2 tabelspoons ketchup
2 tablespoons vinegar
1 teaspoon salt
1 tablespoon olive oil
You can use a pressure canner at 10 psi for 90 minutes, or the way i do it is the "water bath" method. Put all jars in a big pot, fill with water to cover the lids. Just finger tighten the lids so pressure can escape and not blow up the jars. Bring this to a boil and once boiled, simmer for 3.5-4 hours.
Im eating a sucker sandwhich as we speak, thats what made me think of this. I went out this past weekend and netted a couple 5 gallon pails of suckers, and i think im going to get some more. I ended up with 20 pounds of canned meat, but i still have about 15 jars left. Im aiming to fill those up as well.
If you've never tried canned sucker, you're missing out!
