Flädlesuppe - this humble soup made with clear broth and pancake strips is a simple and soul-warming dish. The perfect recipe for leftover pancakes, it is a simple dish to make as a starter. A traditional German soup to make on a budget, yet filling and satisfying.
Wash the vegetables and chop the carrots, leeks, garlic, and root celery.
Place the vegetables with the herbs into a large pot and fill with 2.5 liters / 11 cups of cold water. Bring the pot to a boil, and then reduce to heat to let it simmer for approximately 90 minutes.
Add salt to taste and then drain the broth in a fine sieve or cheesecloth.
To make the Pancakes
In a large bowl, whisk together the flour and the milk until you can no longer see any lumps. Add the eggs one by one.
Finally add the sugar, salt, and carbonated water and mix again until you achieve an even pancake batter.
Leave the dough in the fridge for at least 30 minutes. This allows the gluten to develop and will help the texture of the pancake.
Heat the butter or oil in a coated frying pan on medium heat. Once hot, add the batter with a ladle to the pan.
Cook the pancake until the bottom of the pancake is cooked, which should take approximately 2 minutes. Then turn the pancake and cook on the other side for 2 minutes. Repeat the process until the batter is used up.
Assembling the soup with pancake strips
After the pancakes have cooled down a bit, roll them up and slice them into thin strips. Place in a bowl and then pour over the hot broth. Sprinkle with fresh herbs such as parsley or chives. Serve hot.
