I got this recipe when I bought some Reny Picot brand edam cheese. It's a very mild cheese and tastes VERY similar to cheddar with only a hint of an aged taste. If you like cheddar cheese, you'll like this cheese too. If you've never worked with leeks before, they look like big green onions. You want only the green parts so start cutting near the top of the white. I cut them just like I would green onions.
