You are going to need (for 1 person) :
2 little potatoes or a bigger one (photo)
5 cl of cream (heavy cream)
Step 1: Prepare the Leeks and the Potatoes
Cut the leeks sheets as on the photo.
Step 2: Prepare Leeks, Part 2
Then rinse up all your leeks under water.
Leeks are going to lose their water in the soup, so you don't need to put to much water.
Cover. Then heat up !
Step 4: Mix All
Blend the leeks.
Peel the potatoes.
Add the potatoes to the soup and blend it again, until thick and smooth.
Add salt and pepper to your convenience. If you think it can use a little more water, add water.
Step 5: Add Cream. It's Ready !
And because it's a french recipe from north of France, of course you should eat it with some bread. Maybe you can try a to cook a bread from the bread contest.
