I decided to add them to my garden and have found them easy to grow. Being in Florida planting leeks in fall is advisable. They are a cool weather crop and i don't imagine they would be ready before the warm weather in spring hit. Leeks don't need a lot of room but do grow fairly tall. Here is about as simple a soup recipe you can get. Next time you are at the supermarket, pick them up and give it a try.
4 cups chicken broth
1 cup heavy cream
3 tbsp butter
In a pot add the butter. Cut up the leeks and add them in, sautee the leeks for about 8 minutes. Add the 4 cups of chicken broth and cook for about 20 minutes. Lastly add the heavy cream. Cook another 10 minutes and you are done.
A couple of variations of these would be to use bacon instead of butter. Using the bacon fat to cook the leeks in and adding the crumbled bacon back in at the end. Another variation uses potatoes, but cooking them till tender in the broth for about 20 minutes. Or combine them and get a tasty and filling meal all by itself. No matter which way you do it leeks should be on the menu. Enjoy!
