Jamaican jerk chicken

NOTE: Thanks for the formatting, Ms. Huis!
I'm pretty sure I've served this to most of you at some point over the years. Made it again yesterday for a Gewurztraminer tasting, and realized I hadn't even posted the recipe here. "Everything but the kitchen sink" is a little too vague, but not far off the mark.

Combine in a large bowl:
1 T allspice
1 T thyme
1 1/2 t cayenne
1 1/2 t black pepper
1 1/2 t sage
3/4 t nutmeg
3/4 t cinnamon
2 T salt
2 T garlic powder (I often substitute fresh garlic and add it with the onions below)
1 T sugar

Slowly add:
1/4 cup olive oil
1/4 cup soy sauce
3/4 cup white vinegar
1/2 cup orange juice
juice of one lime

Add: 1 habanero pepper, seeded and minced
1 cup chopped white onion
3 scallions, finely chopped

Marinate 4 chicken breasts for at least one hour. Grill, basting with marinade as necessary. Meanwhile, boil leftover marinade and serve as dipping sauce.
