Dissolve the Bactoferm F-RM-52 starter culture in distilled water and let it sit for about 20 minutes to activate.
Mix the Meat and Seasonings:
In a large bowl, combine the diced or coarsely ground beef with kosher salt, curing salt, dextrose (or sugar), black pepper, red pepper flakes (if using), fennel seeds, and minced garlic.
Pour in the red wine and the activated starter culture solution. Mix thoroughly until all ingredients are well incorporated and the mixture becomes sticky, indicating proper protein extraction.
Stuff the Casings:
Load the meat mixture into a sausage stuffer and fill the prepared casings tightly, ensuring there are no air pockets. Twist or tie the ends securely.
Fermentation:
Hang the stuffed sausages in a controlled environment at 70-75°F (21-24°C) with high humidity (85-90%) for 24-48 hours to ferment. This step develops the characteristic tangy flavor and lowers the pH, aiding in preservation.
Drying:
After fermentation, move the sausages to a curing chamber or a cool, humid area with temperatures around 55-60°F (13-16°C) and 70-80% humidity. Allow them to dry for 4-6 weeks, or until they have lost about 30% of their initial weight.
Enjoy:
Once properly dried, the beef soppressata is ready to be sliced thinly and enjoyed. Store any leftovers in the refrigerator, wrapped tightly in parchment paper.
