This simple yet very yummy dish gets a down home touch and boost of flavor adding celery! One of my favorite aromatics! Discovered in September 2008's Gourmet Magazine which states "Celery- often dismissed as one of the produce world's poorest relations- contributes an intriguing earthiness to moist chicken infused with the flavors of wine and garlic." If you must substitute the garlic please remember that halved garlic will not release the same amount of garlic flavor that minced does. If using minced fresh garlic I think I would try 1 tablespoon, taste and add more if desired. I calculated servings using one piece of chicken per person. Use any mixture of legs and thighs you prefer. I used 2 legs and 4 thighs. That must have been a weird looking chicken! lol I have had fun playing with this recipe and I have tweaked it a bit to make it even better, I think. Hope you enjoy!
