My brother Dan first told me about these Himalayan salt blocks. I orderd one and it arrived last week. It's very heavy and very cool. I heated it in the oven at 500F for about 30 minutes then put it on a burner. We cooked the shrimp for about 90 seconds per side. There was enough sensible heat in the salt to to two batches. Actually, there was enough to do more, but two was all we had. They were delicious!
