Rubio's Salsa Picante?

So if you have never tried Rubio's Salsa Picante you need to, it is incredibly addicting! Their tacos are pretty good in general but the main thing that keeps me going back there is the salsa picante (this is their "spicy" salsa, the darker red one with black flecks in it), it isn't all that spicy but has a great mix of some heat and flavor... Anyway I have been wanting to get some for home use for a while, I recently stumbled upon a post on chowhound with someone claiming to have found a recipe that tastes the same. Haven't tried it yet, apparently 'frying chili peppers releases a fume that can be very irritating to your throat' so they recommend cooking it outside. Anyway, I will try it soon and see if it is really as good:

1 small can of tomato sauce - any brand is ok
2 T or more of red chili pepper flakes
2 tsp sugar or to taste
Salt 1 T or to taste

Toast/char the chili flakes in a frying pan – don’t burn! They should be dark not burnt
Toss the pan constantly for even charring. I leave the seeds in. Don't let them get to blackend. (I used a small saute pan, non stick)I would lift the pan when it got to hot and tossed the flakes all around. When the flakes are at the dark color you desire:
Add the can of sauce, let it simmer and reduce. Tasting it, it will taste like tomato sauce with the flakes - not good and so you will need to add
salt to taste - I added it a little at a time. Now it will begin to start tasting better
Add sugar to taste- same process a little at a time - keep tasting
Let it continue to simmer and reduce on low then turn it off and let it sit. Add a little water to thin it, not too much!
I then turned the heat back on and let it cook a little longer, maybe 5 minutes stirring it to make sure i like the consistency. I added another pinch of sugar at this point turned the flame off and let it cool. Once it was cool:
Pour salsa into a container and serve with taco salads, tacos or use wherever!
The addition of the sugar made it so much better! And today, it was excellent!

Let me know how you think it compares if you try it! Enjoy! :)
