I debated buying these planks. At $6+ per, they're pretty pricy for cooking implements that can only be used a couple of times. I convinced myself that the expense was a mere bagatelle when weighed against the heady aroma of hickory wafting out of the grill assuring the most lip-smacking smoky pork chops ever.
That's not exactly how it went down.
The package said the boards could be soaked up to 12 hours. Thinking that pork would take a little longer to cook, I soaked these planks for four hours. They warped. That's OK, I thought. I'll just char the concave side first, and then I'll cook the chops on that side. The problem was the warp kept the wood from coming into full contact with the grill. Very little of the plank charred, even after seasoning for ten minutes and cooking for twenty and there was not much hickory smoke flavor in the chops. No doubt this was operator error, but the package did claim the planks could be soaked for twelve hours.
The other thing is that they're pretty short and narrow planks. I realize the dimensions are clearly stated in the product description, but I'm just saying, they're short and narrow. They held two smallish pork chops each with parts hanging off.
In fairness, I'll say the chops were delicious and fulfilled the lip-smacking portion of the fantasy just fine. The planks cleaned up nicely and because of the warping are in good enough condition to use a couple more times, but beware. Don't soak longer than an hour. Your results may vary. We're new to planking, but previous experience with some nice big cedar planks was more satisfactory than with these.
