Consider this recipe and its variations a template for building your own breakfast sausage. This sausage is mildly seasoned and contains the basic ingredients that I believe comprise breakfast sausage.
Thin sheep sausage casings (optional)
11/2 pounds pork butt or boneless country ribs
1/2 pound pork fat
2 teaspoons dried sage
11/2 teaspoons kosher salt
1 teaspoon freshly ground black pepper
1/2 teaspoon dried marjoram
1/4 teaspoon freshly grated nutmeg
2 tablespoons vegetable oil
1/2 small onion, finely chopped
2 garlic cloves, minced
1. If using sausage casings, prepare them as directed.
2. Cut pork and pork fat into 1-inch cubes. Place cubes in a mixing bowl, and toss with sage, salt, pepper, marjoram, and nutmeg. Transfer cubes to a sheet of plastic wrap on a plate and freeze for 30 minutes, or until very firm. While meat chills, heat oil in a small skillet over medium-high heat. Add onion and garlic, and cook, stirring frequently, for 3 minutes, or until onion is translucent. Set aside.
3. Grind meat and fat through the coarse disk of a meat grinder, or in small batches in a food processor fitted with the steel blade, using the on-and-off pulse button. If using a food processor, do not process into a paste, but ingredients should be very finely chopped.
4. Combine ground meat, onion mixture, and 1/4 cup ice water in a mixing bowl, and knead mixture until well blended. Fry 1 tablespoon of mixture in a small skillet over medium-high heat. Taste and adjust seasoning, if necessary.
5. Stuff mixture into casings as described, if using, and twist off into 4-inch links; prick air bubbles with a straight pin or skewer. If time permits, arrange links on a wire rack over a baking sheet and air-dry uncovered in the refrigerator for 1 day before cooking. Alternately, if keeping sausage in bulk, refrigerate mixture for at least 30 minutes to blend flavors.
6. Cook sausages as directed to an internal temperature of 160°F when pierced with an instant-read thermometer or as directed in a specific recipe.
Note: Sausages can be refrigerated up to 2 days or frozen up to 2 months. Once cooked, they can be refrigerated up to 3 days.
