Cut the onions into thin slices and sauté in 3 tbsp. sunflower oil or other vegetable oil over low heat, turning occasionally, until translucent, cool. Weigh the spices, grind the pepper and have ready. Attach the 2 hole disk to the meat grinder, have the food processor ready with the dough hook.
First grind the stewed onions and then the frozen wild boar meat through the 2 hole disc. In the food processor, knead the minced meat with the onions and seasoning with the dough hook for about 3 minutes on speed 2. Then add the salt and mix again for 3 minutes on speed 2.
In the meantime, remove the perforated disc and the mincing knife from the mincer and replace them with the 20-caliber cross and sausage stuffing tube.
Slide the sausage casing onto the stuffing tube, place the sausage meat in the mincer, and fill the sausage casing in a leisurely and even manner. After every 15 cm (or the desired length) twist off the sausage casing filled with sausage meat. This creates the individual sausages. Until grilling or frying, the sausages must be kept in the refrigerator, but not longer than 2 days. The sausages cannot be frozen.
Sour beans: cut the bacon into small cubes and fry in a saucepan until translucent, add the diced onion and cook until translucent. Place the sour beans on a strainer, rinse under running water, add to the bacon in the saucepan and cover with water.
