Recipe(tried): Taquito Sauce (like Olvera Street)

I have been going to Olvera Street since i was a kid over 45 years...I lived in socal for 28 of my 52 years and this is what I have learned.

Boil 4 tomatillos in about a quart of water. Squeeze the tomatillos when soft. also in the the mix cook two yellow peppers cut and add seeds in the mix. 1/2 tsp garlic and salt. cook down about 15 minutes strain the juice into blender with 3 avocados. mix well and salt to taste. Close.. also the taquitos are fried in lard ..unfortunately the secret ingredient in Mexican cooking.
