Octopus In Ranchero Sauce - cooking recipe

Ingredients

2 medium onions
2 heads garlic
4 1/2 lbs octopus (I used baby ones)
2 bunches parsley
2 bunches cilantro
1 teaspoon black peppercorns
4 fresh green serrano chilies
16 cups water
2 cups light beer
6 cups water
16 medium plum tomatoes
1 1/2 medium white onions (peeled and sliced)
6 garlic cloves (peeled)
14 fresh green serrano chilies
1/2 cup olive oil
6 garlic cloves
8 garlic cloves
1/2 cup cilantro leaf
1 1/2 teaspoons salt (to taste)

Preparation

First roast 2 medium onion and 2 heads garlic in the oven (at 425 for 20 minutes or so until they start to caramelize). Alternately you can pan roast them in a cast iron skillet.
In a large pot place roasted onion and garlic, octopus, 2 bunches parsley & cilantro, peppercorns, 4 serrano chiles (whole), 16 cups water and beer.
Boil for 1 1/2 to two hours.
Remove from heat and let the octopus cool in the liquid while you start the ranchero sauce.
Bring 6 cups of water to boil with 16 plum tomatoes, 14 serranos, 1 1/2 sliced tomatoes and 6 cloves of garlic and simmer for 30 minutes.
Strain out the solids (saving the Ranchero broth), puree the solids in a blender or Cuisinart with 1 1/2 cups or the retained broth.
Now, heat 1/2 cup olive oil in a tall thick pot and add 6 cloves of garlic. Simmer the garlic until it turns golden, remove them with a slotted spoon and carefully pour in the Ranchero sauce. This will cause splattering so I strongly encourage long sleeves. Stir like mad for the first few minutes until it's a gentle simmer. Cook for 30 minutes.
Now strain the liquid from the simmered octopus and in a separate pan cook down to 3 cups. This should take about 30 minutes. Meanwhile separate the octopus from the veggies and toss the veggies.
While the ranchero sauce and octopus are simmering down take the final 6 cloves of garlic, 1/2 cup of cilantro and salt and either in a pestle or a blender puree into a smooth paste.
Add the paste, octopus and reduced octopus stock to the ranchero sauce and cook for a final 20 minutes.
I sometimes split this recipe over two days (make the octopus one night and the ranchero the next).
