The overall spiciness of Tinga depends on how much sauce you add. So, if you're concerned about the spice factor, taste the sauce before you add any, then decide how much to add to your chicken (add more for a spicier dish). Keep in mind the sauce tastes spicier alone then when eaten with food. If your Chicken Tinga winds up being a too spicy despite your efforts, serve the Tinga with a dollop of sour cream of lime wedges to counterbalance the heat.
