Start by adding your chuck roast, whole onion, whole garlic, 4 bay leaves and 4 cloves to a big pot. Cover with water and let it simmer for 2 hours.
Meanwhile soak your chiles in hot water for about 20 minutes.
After soaking. Discard that water and place your soaked chiles in a blender with a cup or two of fresh water or the broth your meat been simmering in. Also toss in the rest of your ingredients. Blend this up until smooth!
Now strain your sauce with a mesh strainer. Do this as many times as you like until you get it nice and smooth. I did it twice.
Taste for seasoning. It might taste a bit bitter. I haven’t mastered this technique yet. So add about 1/2-1 cup sugar.
Remove the whole onion, garlic bulb, bay leaves and cloves from your meat thats been simmering. Now add your sauce to it. Mix well. Let this simmer for 30 minutes to 1 hour. I noticed when I let it simmer longer the flavors were better.
Carefully take your meat out and shred it up.
I got another big pot and strained the sauce one more time!
Now the fun part. Dip your tortillas in the sauce and pan fry on medium heat with a little bit of oil on each side for 1-2 minutes. Add in your shredded meat, with some cheese and fold it over like a taco.
10. Garnish with raw onion onion and cilantro. Spoon the sauce in a bowl and dip your tacos! Thank me later!
