Soooo I tried making a version tonight and it isn't exactly the same as what I had at the restaurant but it was DELICIOUS. I actually think I like it better than what I had at Veneno and I can control the heat and sodium this way.. Here's what I did and it yielded about 2 cups of "sauce"...
I used...
1/2 cup Vidalia (sweet onions)
1 Roma Tomato
4 Oz tomato sauce
2 garlic cloves
2 Knorr Chicken Bullion Cubes
1 package of Goyo Sazon'
1/4 cup margerine
1 small package of dried chile de Arbol
1 small package of dried Chile de Guajillo
In one pot I put 2.5 cups of water and set it to medium high/high heat to boil. I added the sliced sweet onions to it, the chicken cubes, garlic cloves smashed with the flat side of a knife, and the roma tomato sliced thin. I let this boil covered until the tomato completely disappeared then put the temp down to medium to simmer.
In another pot I put about 6 chile de arbol and about 4 Guajillos and a few cups of water (just enough so the peppers are floating). I guess you could use the powdered versions of the peppers and just add that to the broth in the first pot above but I like doing it this way. If you like things spicy use more peppers and leave the seeds in. I took out most of the seeds and took the stems off of course and it still had good kick after it was all done. I let those boil until soft, about 6 minutes. Then I use tongs and take them out of the pot and put the peppers into a blender. I add about 1 cup of broth from the first pot to the blender and let it blend until its a pepper smoothie. I then strain the mixture into a measuring cup and pour the strained pepper liquid into the first pot. I let that simmer on medium for a few minutes and its ready to pour over your crab or shrimp or just put it in a side cup and dip your crab into it. It's pretty darn tasty. You could also make this recipe in a bigger batch and put whatever in it as a stew.
Let me know what you all think if you try it!
