This is a traditional Belgian smoked and fermented sausage that's on the EU list of PGI European certificates of origin. Mild and gently seasoned, it's great if you like the smoke flavour in dry cured sausages. The saucisson I made is made with pork only, but some variations also include beef.

Recipe for 1kg of meat
Meats
750g class I pork from leg and and loin, no fat or connective tissue
250g hard back fat
Ingredients
22g fine sea salt
3g Cure#2
2g granulated garlic
1g cumin
1g mace
1.5g crushed juniper berries
2g dextrose
1g sucrose
0.3g Texel DCM-306 starter culture
Process
1. Cube meat and fat, mix with salt, Cure#2, and refrigerate in a sealed container for 48 hours.
2. Freeze fat completely, leave the cubed and cured meat in freezer for one to two hours so that it it freezes partially.
3. Revive starter with small amount of distilled water and a pinch of dextrose. Add to meat within 20 minutes.
4. Grind everything through 6mm plate. Do not grind fat separately.
5. Mix starter culture and spices with the meat. Keep ground meat cold, mix thoroughly, taking care not to over mix to avoid fat smearing. You may want to refrigerate the meat between the grinding, mixing and stuffing steps.
6. Stuff into 45-50mm beef middles. D'Ardenne may also be made in large diameter casings.
7. Ferment at a temp of 18-20C for 48-72 hours, until pH drops to 5.2 or slightly lower.
8. Cold smoke in two 8hr sessions over 2 days, taking care not to go over 20C. I also added juniper berries to the smoker.
9. Hang for approximately 4 - 5 weeks at 12C and 75-80% RH, until a weight loss of 35%. Weight loss is calculated from the weight of the sausage after stuffing.
10. Mould is not desired on this sausage. Mine took some on after about two weeks in the chamber and I left it on.
