Prepare your ingredients. If you're using fresh milled flour, mill about 140 grams of wheat berries. Pull your starter out of the fridge.
Whisk all ingredients in a large bowl.
The dough should come out quite thick and sticky.
If you're making dumplings as part of a soup or stew, prepare the soup until the point of simmering on the stovetop. If not, bring a pot of water to a simmer.
Over low-medium heat drop your dumpling dough using a tablespoon or cookie scoop into the pot of soup or water.
Drop each dumpling separate from eachother - you'll want to make them in two batches so they don't stick together. Place about 4-5 in the first batch and 4-5 in the second batch.
Using your scoop dunk your sourdough dumplings underneath the liquid so it runs over the top of the dumplings.
Place your lid on your pot or dutch oven and let simmer for about 15 minutes.
Remove the lid and using a wooden spoon, remove your dumplings. Drop the next batch in the liquid, cover and cook until done. Using a ladel, scoop some of your soup with a dumpling or two into a bowl!
