Place pork in a bowl and season liberally with salt and pepper. Combine baking soda and wine in a small bowl and add mixture to the pork along with the finely chopped garlic, onion flakes, oregano, sage, red pepper flakes, smoked paprika, fennel seed and allspice. Combine and chill at least 1 hour up to overnight. Form 4 patties that are thinner at the center for even cooking.
Bring a few inches of water to boil. Add salt and blanch the broccoli rabe for 2 minutes. Transfer to an ice bath then dry.
