This is one of my favorite soups. My mom often made it when I was a kid...but now I can made one myself.

Products:

1 kg potatoes (about 10 medium size)
1 onion
1 or 2 carrots
Oil
Salt
Pepper and any other ingredients you like
1 to 2 litters Water
1 egg

Optional

Toast
White cheese

Step 1: Cut the Vegetables

Peel the potatoes and slice them. Do the same with the onion and the carrots. I use frozen carrots so I’m not going to slice them because they are already grated.

Step 2: Boil

Put the products in the water and add the oil, the salt and the pepper. If you like other ingredients put them now.
Then place the pot to the stove and wait until the water boils. My potatoes are ready for about 15-20 minutes, but it depends on the stove.

Step 3: Stir the Egg Into the Soup

When everything is ready leave the soup 10 minutes to get cool. Meanwhile you can whip the egg.

Here's how I made it:
While I stir the egg, I slowly add some of the water (only water, no potatoes) from the soup. I'm adding water until the bowl gets full. Then I add the egg into the pot with the other products.
