I wandered into Target's patio section and spotted some cedar planks: 4 for ~$12. They were about 12 inches long. But then a couple of questions came to mind as I looked at them:
1. How do you serve your fish...I've had short planks set on a plate in restaurants, but I don't have serving dishes that will hold a 12" plank.
2. The directions said to discard after cooking. Do you really have to throw these away? I thought they were reusable.
