I like to marinate in a mix of soy, brown sugar(a lot, enough to off set the saltiness of the soy), mirin, ginger, garlic, sesame oil, green onions, and cilantro. Make the marinade separately, and reserve some of it, as it cooks down wonderful, and add a little crushed red pepper flakes. . .anywho, marinate your bird(boneless skinless thighs for me), 6 hours is good, over night is better, and sear off really well, finish in the oven, then julienne, toss with some sweated diced peppers and onion, add some of the reserved marinade that you have cooked down a bit and thickend with a slurry, and viola: The best "Bourbon" Chicken you have ever had.
For a more laid back, easy breezy marinade, I use this for almost all of my airline stlye chicken breasts: Balsamic, lemon zest, minced basil, minced rosemary, minced garlic, and olive oil. I typically put the bird boobs in a large zip top freezer bag, add the marinade, and massage the bird until well worked, and just let 'em be. Again, 6 hours is good, over night is better. Grill 'em, pan sear 'em, it's all good.
I like to take prefab Jerk Seasoning(dry), mix in just enough Sweet Thai Chili sauce to make it a paste, add a hand full of chopped green onion, a little vanilla extract, 2 whole star anise, a splash of cider vinegar, and marinate 8 cut chicken for a day. Best over a charcoal grill, and simple garnished with caramelized pineapple, and cilantro.
Beer can chicken, just Google it, that should keep ya busy for a month or two. The marinades run far and wide, but the technique is GREAT. Instead of using beer, I use margarita mix, with a bird that has been marinated with Onion, garlic, cilantro, lime, pepper, oil, tequila, cumin, chili powder, and sea salt. Margarita Chicken anyone?
