I'm glad we dug potatoes while it was nice out because it has rained every day since! I have potatoes that I am sorting by size. I love the smaller poatoes for canning them. Canned potatoes make delicious fried potatoes!!! I scrub them with a vegetable brush, and leave the skins on. I might get some Red Pontiacs that have a heavy skin, but that'll usually come off while frying....and besides the skin is where the nutrients are, so I've heard.
Sort, wash, leave skins on. Boil for about 5 or 10 minutes. Pack hot into hot jars, cover with boiling water, leave headspace. Add 1 tsp salt to each quart.
Process in a pressure canner 40 minutes at 10 lbs pressure.
