You can use garden or store potatoes to can. Our potato plants died to soon, so we did not get the crop we usually get. So when potatoes go on sale, I will buy a bunch and can them.
These are our new potatoes dug this year. The small ones, I wash really good and can. These are good when it’s cold outside.
The above canned potatoes are from this year. The below are from last year. The starch (the white coating on potatoes below) is just washed off, and potatoes are good. The chopped potatoes are used in : beef stew, put in a pan and fried with butter and onions, in a pan and eaten as boiled potatoes, drained over night and used in potato salad, and more.
To pressure can Potatoes:
(are a low acid food and must be pressured canned to destroy all bacteria and etc.)
Small ones: just wash well and pack loosely in jars.
Large ones: Peel and cut into a brine water ( 1 teaspoon salt to a quart of water) , then rinse and pack loosely in to jars.
Then add 1 teaspoon of salt per quart and fill with water.
Process 40 minutes for quarts at 15 lbs.
For those of you who do not have a pressure canned, the potatoes can be froze, put in the cool part of your refrigerator. But please do not use a hot water bath canner as it is not safe.
