So once you get it wet again, it's still as nutrient loaded.
Cooking doesn't require the drying process, and focuses more on the trapped debris/nutrients as once you get rid of them, you have no food for the algae and it cannot live. In a sense, it ignores the algae [as opposed to drying] as once the nutrients are gone the algae will remove itself.
I agree with Mark. I would think drying would actually leave more nutrients. When the algae is alive it contains nutrients. Once it dies those nutrients are released. The rock would absorb some of the nutrients potentially. Also you would have nutrients from the dying life within the rock that would be released.
