Detective Pux here, and I'm here to show you how to make the perfect Kartoffel Knödel from scratch. But before we get into the recipe, let me first explain what a Kartoffel Knödel is.

A Kartoffel Knödel is a traditional German dumpling made from grated potatoes. It's typically served as a side dish with gravy, but can also be served in a bowl of hot soup. They're a staple of Bavarian cuisine, but can be found throughout Germany.

Now, for the recipe:

Ingredients:

• 1 lb of potatoes, peeled and grated
• 1/4 cup of flour
• 1 egg
• 1/4 cup of breadcrumbs
• Salt and pepper, to taste
• 1/4 cup of flour (for rolling)

Instructions:

1. In a large bowl, combine the grated potatoes, flour, egg, breadcrumbs, salt, and pepper. Mix well until the mixture forms a dough.
2. Form the dough into balls, about the size of a large orange.
3. Roll the dumplings in flour and place them on a plate.
4. Bring a pot of salted water to a boil. Gently add the dumplings to the water and let them cook for about 15 minutes.
5. Remove the dumplings from the water using a slotted spoon and let them drain.
6. Serve the dumplings with gravy or in a bowl of hot soup.

And there you have it, the perfect Kartoffel Knödel from scratch. Now, if you'll excuse me, I have to go solve a case. But before I go, let me leave you with one final piece of advice: don't skimp on the salt and pepper, it really makes a difference in the flavor. And remember, if it's not perfect the first time, don't worry, it's all part of the detective work. Happy cooking!
