As I have said before we get potatoes once a year ( we tried to grow some but the prairie dogs ate the all) They will keep for quite a while but not all year. So I dry a bunch of them to use in stew, scalloped and to mash. I also freeze a few for frying. I am going to try and rehydrate some this year to fry and see how that works.
The first thing is get your potatoes these potatoes were so big, Ilove them for doing things like this. Peel and wash them.
Slice into about 1/8 inch slices I use my mandolin which I love.
Put them in cold water after you slice to keep from turning brown.
After you get all them sliced put in to boiling water for about 5 to 6 minutes.
After you blanch them put straight into cold water.
I add some ice to help keep the water cold so they will not keep cooking.
Drain well, I drain mine then put on a towel to help dry them off a little better. I forgot to take a picture of that.
Then put on your trays and dehydrate at 120 for 18 to 20 hours until brittle and semi transparent.
Make sure they are dry any little bit of moister will cause them to mold.
1 cup of dried potatoes will equal 1 to 1 ½ cups cooked potatoes.
