It was my intention to stuff it at home too. But I decided against it when I realized that the stuffing attachment for my Kitchenaid stand mixer would ruin the texture by pulverizing the fat -which I wanted to remain in ~1/4" chunks- as it worked along the worm gear. So I took the forcemeat to the farm and expressed it into hog casing with the piston stuffer then brought it home to age.
Salami Stuffing Process
At the farm I always age the meat in the cheese aging room which is well controlled for humidity, temperature and air flow. But whenever I've aged meat at home in the past, I've winged it by hanging it in the basement and crossing my fingers. Well, I've decided not to do that anymore and build an aging room. But before I start shooting nails into the foundation and putting up studs I'm going to tinker around with different prototypes by way of determining how big the room needs to be, how often the air needs to turn over etc.
Here is my first prototype aging room. I put it up on Saturday in about an hour. Humidity is controlled by a vaopirizer hooked up to a timer. The air is turn over twice a day by a small fan (also on a timer). I expect that future versions of this will include a larger humidifer with a humdistat and a larger much slower turning fan.
