Score the base of each tomato with a cross. Place tomatoes into Varoma dish. Pour water into Thermomix bowl and steam tomatoes 10 min/Varoma/speed 4. Cool tomatoes by plunging them into iced water. Peel. Drain water from the bowl.
Place onion, garlic, coriander and chili into Thermomix bowl and chop 2 sec/speed 6. Scrape down sides of bowl.
Add remaining all ingredients (do I have to specify this?) other than Corn Chips but including tomatoes into the Thermomix bowl and cook 60 min/80ºC/speed 2. Cool completely.
Now to the flame grilling discussion: Place whole chilli on an open gas flame and turn it a few times until it is charred and the flesh is soft. This will not take ages, but nor will it take seconds. When you are happy that it is well charred, place into a glass bowl, cover the bowl with plastic wrap and allow the chilli to sweat. Rub the blackened skin off prior to using in the recipe. This will add a lot of flavour to the salsa.
Serve with diced avocado as a garnish and with lots of corn chips…or toasted tortilla wedges, or as the sauce for char grilled chicken or beef strips wrapped in soft tortillas; you see where I am going with this? Its another pantry item…yes, I think so!
