Step 1

Remove the eyes and peel the potatoes.

Step 2

Chop them into pieces and place them in a large bowl or sink full of cool water to prevent oxidation. Some places say to add lemon juice, but I found it wasn't necessary.

Step 3

Bring a large pot of water to a boil, add the potatoes, and parboil them for a couple minutes.

Step 4

Drain the water and rinse the potatoes with hot water to remove starch. (Unless that sort of thing doesn't bother you.)

Step 5

Spoon the cubes into clean quart-sized mason jars and fill the jars with hot water, leaving 1" headspace.

Step 6

If you'd like, add 1 teaspoon of salt to each jar.

Step 7

Wipe the rims and then top the jars with clean rings and lids.

Step 8

Pressure can according to manufacturer's directions at 10 pounds of pressure for 40 minutes.
