Cut the meat and fat into 1 inch cubes. Freeze the cubes for about 30 minutes to firm them up before grinding.
Grind the meat and fat together through the coarse disk of a meat grinder.
In a large bowl, combine meat, salt, black pepper, fennel,garlic, wine, brandy, vinegar, and crushed red pepper. Mix well, using your hands.
Refrigerate, covered 3 to 4 hours. This gives the wine and brandy a chance to extract maximum flavor from the herbs and spices and for the meat to absorb some of the liquid.
Before you start making your patties fry up a small patty of the mixture to make sure that it's seasoned the way you want it.
Place the patties on a platter, cover, and refrigerate for a couple of hours or overnight to meld the flavors. Use within 2 to 3 days or freeze for up to 3 months. We froze them using our new Food Saver!
