You place chopped, diced leeks in a BIG bowl of cold water. Swish it around. They are really dirty and this is the best way to wash them.
See all that dirt left!
4-cups of broth- I use chicken, vegetable could be used too
1TBS of cornstarch
4 cups of peeled and diced potatoes
1 cup half n half
1 cup milk (or cream- depending on how low in fat you want your soup)
1 package of diced pancetta
First add a swirl of olive oil to a large skillet. Heat that to medium. Add in the sliced leeks and garlic and saute until leeks are tender.
Pour broth into a large pot and add cornstarch before turning on the heat. Add potatoes and then turn on heat to medium high. Add leeks to broth. Bring to a light boil.
In the saute pan you used for leeks, dump in the pancetta and brown slightly to your desired crispness.
