Preheat your oven to 450 degrees
Slice peach in half, removing the pit. You don't need to peel the peach.
Roast in the oven for 15-20 minutes until soft and starting to brown. Set aside to cool.
Place the peach in a food processor, puree to smooth, or if you like it chunky, give it a few pulses.
Mix in the rest of the ingredients.
Taste. Adjust if needed with more of any of the ingredients.
