So, I did a dozen wings this way. Olive oil and 2 TBS HDD. Let them marinate for about an hour. I sprinkled a couple pinches worth on after I pulled it from the marinade, but left it at that. The other dozen I did with lemon juice, pepper, and salt. Grilled them as mentioned on my gasser. They did come out really nice. Cooked through, crispy skin. I probably could have used more HDD. They had heat, but weren't too hot. Could taste the salt and the celery. We both detected the sweet too.
I'll make these again, but go a little heavier on the HDD. Thanks for the recipe and the HDD! Great product.
