This marinade is truly a "powerhouse" of flavors! With 13 ingredients, I can't imagine we left anything out. It's sweet, spicy, tangy, savory, tart, garlicy... did I miss anything?
You can certainly use this marinade on any chicken or even beef, but the leg-thigh quarter is a favorite of our family when it comes to grilling. That entire grilled chicken quarter is reminiscent of big church picnics where we could buy a "chicken dinner" to help support the school, and the chicken was a leg-thigh quarter grilled on an open fire. That's just a fun memory and that's why we like to grill chicken quarters.
