I thought it was enough to put my cedar plank over aluminum foil and the burners to the lowest setting... luckily, I had the temperature probe in the salmon, so I noticed the flare up right away and it came out not much darker than in the picture.
Hey !food, wanna share a kitchen disaster in the comments?
I had a big pink salt block, and I'd heard you could use salt blocks directly on heat to cook. Warmed it up, got really excited... Found out that the salt block has to be particularly selected and tested or it will explode along fault lines, loudly and dangerously all over your kitchen.
For cedar planks you wanna soak them in water for a few hours first my friend
Thank you so much for preventing me from doing the same thing someday, because I own such a block and am an idiot
