Cost: $17.86 total, $4.47 per serving

Ingredients

  • 1 pound Ground Beef (100% lean, fresh)
  • 11 pieces Thai Bird's Eye Chilies (Whole, keep seeds for heat)
  • 14 cloves Garlic Cloves (Peeled)
  • 1 package Nimju Seasoning Mix (Contains salt blend and yeast)
  • 0.25 cup Granulated Sugar (Standard granulated sugar)
  • 0.5 teaspoon Salt (Regular table salt)
  • 4 drops Red Food Coloring (Liquid food coloring)
  • 4 ounce Cooked Sliced Pork Skin (Pre‑cooked, sliced, boiled then shredded)
  • 1 24-pack Mountain Dew (or citrus soda) (Used as weight and flavor during fermentation)
  • 1 roll Aluminum Foil (Heavy‑duty)

Instructions

  1. Prepare Pork Skin

    Bring a pot of water to a rolling boil, add the sliced pork skin and reduce to medium heat. Cook for about 5 minutes until the skin is firm but not mushy. Drain in a colander, rinse with cold water, then shock in an ice‑water bath. Drain again, cut any overly long strands, and squeeze out excess water with your palms.

    Time: PT10M

    Temperature: Boiling

  2. Process Chilies and Garlic

    Place 7 Thai bird’s eye chilies and 7 peeled garlic cloves in a food processor and pulse until finely chopped. If you don’t have a processor, smash them with a heavy object in a bowl. Slice the remaining 4 chilies into thin circles and the remaining garlic cloves into tiny discs.

    Time: PT10M

  3. Season the Beef

    In a large mixing bowl, combine the 1 lb of lean ground beef with 4 drops of red food coloring. Add the whole Nimju seasoning package, the processed chili‑garlic mixture, ¼ cup sugar, and ½ tsp salt. Using clean hands, massage the mixture for about 10 minutes until the seasoning is evenly distributed and the texture becomes slightly sticky.

    Time: PT15M

  4. Incorporate Pork Skin

    Add the prepared pork skin to the seasoned beef and knead briefly (about 2 minutes) until fully integrated.

    Time: PT2M

  5. Assemble in Tray

    Line a 2‑inch‑deep baking tray with a sheet of aluminum foil. Transfer the beef‑skin mixture onto the foil and press down to form an even, compact layer. Top with the sliced garlic discs and chili circles for extra visual appeal.

    Time: PT5M

  6. Weight and Add Soda

    Lift the foil with the meat brick out of the tray, wrap it tightly with another sheet of foil to form a sealed “brick”. Place a heavy rectangular object (e.g., a book or lid) on top, then set the 24‑pack of Mountain Dew on the weight. This adds pressure and a subtle citrus note during fermentation.

    Time: PT2M

  7. Ferment at Room Temperature

    Leave the wrapped brick at room temperature (around 20‑22 °C) for 24 hours. The Nimju mix’s salts and yeast will dehydrate and ferment the meat safely.

    Time: PT24H

  8. Chill and Serve

    After 24 hours, transfer the foil‑wrapped brick to the refrigerator for at least 2 hours to firm up. Slice into thin pieces and serve as a spicy, salty snack with beer or as part of a charcuterie board.

    Time: PT2H

    Temperature: 4°C

Critical Success Points

  • Boiling and shocking the pork skin to achieve proper texture.
  • Hand‑mixing the beef mixture for at least 10 minutes for even seasoning.
  • Ensuring the foil is tightly sealed before fermentation.
  • Maintaining a 24‑hour fermentation period at room temperature.
  • Chilling the brick for at least 2 hours before slicing.

Safety Warnings

  • Handle raw ground beef with clean hands and sanitize all surfaces to avoid cross‑contamination.
  • Ensure the Nimju seasoning contains enough salt and yeast; insufficient salt can allow harmful bacteria.
  • Do not ferment in temperatures above 25 °C for the full 24 hours; high heat can cause spoilage.
  • Keep the foil tightly sealed to prevent exposure to airborne contaminants.
