Give this recipe from the Pioneer woman, a try.
You will not be sorry.
The chopped leeks are added to the pancetta which has also been chopped. I followed the tip to add a pat of butter.
I just can't not add the butter. Butter just makes it better.
Butter, butter, butter.....butter. There. I'm over it. I think.What you've seen is also mixed with a little white wine, Parmesan shavings, salt and pepper, and some creme. Oh, and the pasta.
For something so very tasty, this gets put together very quickly and easily.
