For my first experiment with this soup, I used both diced and sliced dehydrated potatoes.
I had received a free ten pound bag of Russets in the fall of 2020. With just the two of us, that was more than we could eat before it would go to ruin. So I bought a dehydrator and got to work. The mandolin is helpful with slicing of vegetables. I made the potato slices 1/8th inch thick. The dice was roughly a quarter inch dice. In order to keep the potatoes from turning an off color, after slicing and dicing, I put them into a pot of boiling water to which I had added the juice of a half of a lemon. They stayed in the water about 4 minutes. Then, with a spyder ladle, I lifted them out and into ice water to stop the cooking. Then I drained them thoroughly and patted them dry before putting onto the shelves of the dehydrator. It takes about 6 -8 hours to dehydrate the 6 shelves of potato slices at 165 degrees Fahrenheit. I then loaded the potatoes into quart mason jars and used a Food Saver type machine with a “wide-mouth” jar device to seal the jars. Then into the pantry they went.
To rehydrate, I put them in a bowl and poured warm water over them. In about 10 minutes, they were ready to add to the soup. It turned out beyond delicious! It also cut the time it took to make the soup because the potatoes were partially cooked.
The other ingredient I want to emphasize is the broth. I used a home-made celery broth. Every time I buy a stalk of celery, I make every effort to buy with a lot of greenery on the ends and the interior. Everything I trim from the individual stalks goes into a pot of boiling water. Sometimes I add other vegetables, but mostly we like the celery broth straight up. I do not add salt, spices or herbs to this broth. I try to keep it as neutral as possible. I save other trimmings of vegetables for a vegetable broth (carrot peelings and ends, onion bits, radish tops, turnip tops, broccoli stems, etc.). I will have a section on broths shortly posted here.
