With Cooks being made in Indonesia, I was curious to find out what they mainly use for making charcoal. It seems coconut shells are very common there for charcoal products.
I think it's very possible that Cooks is made from coconut shells. It would explain the mild smell, and slowish start up. I still have an old bag of Coshell, maybe I can compare the two.
Also, when Cooks charcoal is Googled one hit is WalMart, but when you click it shows a bag of Coshell, out of stock. For whatever that's worth.
