Get your ingredients
Put a non-stick pan or casserole, at medium fire
Chop the onion into relatively small pieces and add them to the pan
Mince the garlic
Chop the onion
Once the onion is caramelized (about 5 minutes) add the garlic
Remove the stems and most of the seeds of the dried chilies and chop them into small pieces. If you are using fresh chilies, do the same, but add half the quantity as I found them more spicy
Add the chilies and the coriander
Reduce the intensity of the fire and stir everything from time to time with a wooden spatula
Chop the tomatoes in squares and continue stiring from time to time
Add the tomatoes and stir very well. Cover with a lid and let it simmer for about 20 minutes
You'll have to "mash" the tomatoes once they have been softened
Let the sauce cool down and use it on everything!
You can blend it, but I actually prefer to see and feel the texture of all the different ingredients!
Enjoy!
