Pseudo recipe:
4.25 pounds pork shoulder and pork belly mix
1 onion and 3 cloves garlic (ground with meat)
4 teaspoons kosher salt (= one heaping tablespoon)
1 tablespoon whole black pepper, ground
1 heaping teaspoon whole cumin, ground
1 heaping teaspoon Mexican oregano
1 teaspoon coriander seeds, ground
1 heaping teaspoon paprika
1 teaspoon red pepper flakes
1/2 teaspoon cayenne
7 ounce can of Herdez Salsa Ranchera (the jarred stuff is not as good)
Notes: Ground once through a 3/16th die. I probably forgot some of the spices I put in, and the quantities may be off, but for the love of Pete, this is good stuff. The addition of vinegar would add a nice balance.
