I watched the video and decided to use herbed butter under the skin of a chicken that I put on the rotisserie. The chicken ended up tasting OK but the skin was not crisp. I read somewhere that butter has a fair amount of water in it, and that is what causes the non-crispy skin. I'm wondering if Franklin's turkey's skin was crisp. A lot of the BBQ pros aim for "bite through" skin and that's not crispy. Maybe Franklin gets bite through with his butter approach?
I'm going to smoke a turkey on my Weber Genesis using apple wood. I'll substitute herbed olive oil for herbed butter under the skin, then dry brine with salt only overnight, then herbed olive oil on the surface of the skin. I'm aiming for nice smoked flavor, tender and juicy meat, and crispy skin. After cooking Thanksgiving turkeys for almost 30 years, I've never been able to achieve all three, but I keep trying!
