Preheat oven to 200*C.
Throw the onion and nectarines in the food processor and process. Then add the chorizo sausage meat. Like I said, I emptied the sausages to make this. Also - because it was ready prepared sausage meat, I avoided adding any other spices. Keep it simple! (For once.)
Process a bit and then, in a separate bowl, mix the onion, nectarine, chorizo mix with the ground pork. Mash about with your hands until well mixed. Then add the chipotle powder and mix it lightly with a wooden spoon or something.
Form the mixture into the portions you want. I made about 12 muffins in a silicon muffin tray.
Bake in the oven for about 35 minutes.
Then, here's the trick.... These are fatty, so when they are baked, I pulled them out of the muffin trays, leaving all that grease behind, and stuck them on a wire rack upside down in the oven and baked for another 5 minutes. This allows the fat to drain off for a less fatty snack. Chorizo can be very very fatty.
Enjoy hot or cold!
