This was the toughest chicken I've EVER had. I prepared this according to the recipe (HTG pg 220):
marinated the chicken
heated the grill to medium
placed the chicked skin-side down
cooked 15 minutes with lid closed (HTG says 12-15 for each side)
turned chicken, added reserved marinade, and grilled another 15 minutes
HTG said the chicken should be 180 degrees and it was 110. The outside was cooked to perfection. I had to reduce heat and cook for another 45 minutes to get 180. The chicken had a great flavor but was so tough it didn't chew well. The dog is eating a half chicken today!
What did I miss?
