For chilli lovers - this style of hamburger is from New Mexico and it involves a plain burger pattie served with an amazing green chilli sauce.
Steps 1 and 3 may both be done ahead of time and the patties and topping stored in the refrigerator for up to 24 hours. Allow the patties to come back to room temperature for 30-45 minutes before barbecuing and re-heat the topping in a pan before putting it on the patties.
I used fresh chilies from the garden - some were fully ripe and red, others were green and more spicy. A fun burger with great zip. - 23 Sep 2015
