Argentine Chorizo

Last month Aaron made some chorizo.  Eventually he wrote down the recipe so he could remember and I could post it. It's in metric measurements because that's how he got the recipe, and that's how he'll make it in the future.  I love that our kitchen scale weighs both ways.
 
• Pork shoulder roast, 8 kg
• Pancetta, 2 kg (could substitute other fat)
• 25 grams paprika (I used a mild version)
• 25 grams ground white pepper
• 10 grams oregano
• 170 grams salt
• 3 garlic cloves (minced)
• 200 ml apple juice or cider
 

1. Using a meat grinder with a large (8-10 mm) plate, grind up the pork and the pancetta and mix well together. Add the dry ingredients and mix into the meat. Add the garlic and apple juice and knead the mixture between your fingers until it begins to stick together (5-10 minutes). 
2.  Prepare hog casings per package directions and rinse well with water. Thread the casings onto the sausage-stuffing tube and start slowly filling each chorizo, twisting the casing when it reaches about 4-5 inches long (or the desired length). Let rest a few days in the fridge and then cook or freeze for later use.   

 Note: The best way I (Aaron) found to cook them is to boil them first until at 160-165 degrees and then smoke on the grill for 5-10 minutes.
