The chutney can be very versatile, and other fruits can easily be added for the different seasons; for example, fresh nectarines in summer, plums in late summer or pears in the fall. You can swap out the peaches or apples, or add smaller amounts of different fruit; this way, your spice profile will still be accurate. Mangoes are also a great addition to chutney. If going the tropical route, adding 1 cup of pineapple juice to the BBQ sauce could be fun; just add to the bourbon before you flame off the alcohol. The most important thing is to enjoy the process!
