Note 1: To easily make sour dough breadcrumbs, take a piece of stale sough dough and grate on a box grater. Voila! You have breadcrumbs!
Note 2: I used the large diamond clams, if you are using smaller clams then you will need to reduce your cooking time. You will know the clams are cooked when their shells are open.
Note 3: Discard any that do not open during cooking, these are not good to eat.
