📝 About This Recipe

Hailing from the historic city of Regensburg, these iconic sausages—locally known as 'Knacker'—are celebrated for their distinctively firm 'snap' and chunky, rustic texture. Unlike a smooth bratwurst, the Regensburger features a blend of finely emulsified pork 'brät' and hand-diced lean pork, seasoned with a secret profile of mace, ginger, and garlic. Smoked over beechwood and then gently poached, they offer a smoky, savory depth that has been a staple of Bavarian butcher shops since the 19th century.

🥗 Ingredients

The Meat Base

  • 600 grams Lean Pork Shoulder (chilled and cut into 1-inch cubes)
  • 200 grams Pork Back Fat (Speck) (very cold, diced)
  • 200 grams Lean Beef (Top Round or Chuck) (chilled and cubed)

The Seasoning Blend

  • 20 grams Pickling Salt (Prague Powder #1) (essential for the classic pink color and safety)
  • 3 grams White Pepper (ground)
  • 1 gram Mace (ground)
  • 0.5 gram Ginger Powder (adds a subtle brightness)
  • 1 gram Garlic Powder (or 1 clove fresh, very finely minced)
  • 150 grams Crushed Ice (to keep the meat cold during emulsification)

Casings and Smoking

  • 1 hank Beef Middle Casings (34-36mm diameter, soaked in warm water)
  • 2-3 cups Beechwood Chips (for authentic Bavarian smoke flavor)

👨‍🍳 Instructions

  1. 1

    Begin by chilling all metal grinder parts and bowls in the freezer for at least 30 minutes. Keeping the meat below 4°C (40°F) is critical for a perfect emulsion.

  2. 2

    Separate 300g of the lean pork shoulder. Hand-dice this portion into very small 1/4-inch (5mm) cubes. Set this aside in the refrigerator; this provides the signature 'chunky' texture of a Regensburger.

  3. 3

    Grind the remaining 300g pork, the 200g beef, and the 200g pork fat through a fine 3mm (1/8 inch) grinding plate into a chilled bowl.

  4. 4

    Transfer the ground meat to a high-speed food processor. Add the pickling salt, white pepper, mace, ginger, and garlic powder.

  5. 5

    Pulse the mixture while gradually adding the crushed ice. Process until the mixture becomes a smooth, pale pink paste (the 'brät'). Ensure the temperature does not exceed 12°C (54°F).

  6. 6

    In a large chilled bowl, fold the hand-diced pork cubes into the smooth 'brät' until evenly distributed. This contrast is the hallmark of the Regensburger.

  7. 7

    Flush the soaked casings with cool water. Slide the casing onto the stuffing horn of your sausage stuffer, leaving a small overhang.

  8. 8

    Stuff the mixture into the casings firmly but carefully to avoid air pockets. Twist into short, plump links about 10-12cm (4-5 inches) in length.

  9. 9

    Hang the sausages in a cool, dry place for about 30-60 minutes to allow the surfaces to dry. This ensures the smoke adheres properly.

  10. 10

    Preheat your smoker to 70°C (160°F). Use beechwood chips for the most authentic flavor profile. Smoke the sausages for about 45-60 minutes until they reach a golden-brown hue.

  11. 11

    While smoking, prepare a water bath heated to exactly 75°C (167°F). Do not let the water boil, as this will burst the casings.

  12. 12

    Remove sausages from the smoker and poach them in the hot water for 20 minutes. The internal temperature should reach 70°C (158°F).

  13. 13

    Immediately plunge the cooked sausages into an ice-water bath for 10 minutes. This stops the cooking process and 'shocks' the casing to create that famous snap.

💡 Chef's Tips

Always keep your meat and equipment 'butcher cold' to prevent the fat from melting, which leads to a mealy texture. If you don't have a smoker, you can add 2 tsp of high-quality liquid smoke to the emulsion, though the color won't be as deep. For the best 'snap,' use natural beef casings rather than hog casings; they are slightly tougher and provide better resistance. When poaching, use a thermometer for the water; if it hits 80°C or higher, the fat inside the sausage will render out and leave the meat dry.

🍽️ Serving Suggestions

Serve 'Regensburger Semmel' style: sliced lengthwise, grilled, and tucked into a hard roll with sweet mustard, horseradish, and pickles. Pair with a cold Regensburger Helles or a crisp Bavarian lager to cut through the richness. Accompany with a traditional Bavarian potato salad (made with vinegar and broth, not mayo). Enjoy cold as a 'Brotzeit' snack with a dollop of Händlmaier’s sweet mustard and a soft pretzel.
