Making a sausage and letting it dry out in the fridge
Yes, from a food safety perspective, this is a terrible idea and not safe.


Shelf life of ground meat
Typical recommendations for ground meat is 1, max. 2 days in the refrigerator. Ground meat has a very large surface area and the grinding step can mix bacteria that previously were only on the surface of a whole piece (and unable to penetrate) throughout the meat.
Salt as preservative
Salt (NaCl) is a preservative, but you need up to 20% of the meat weight, which is far more than your two tablespoons. The preserving effect is acchieved by osmosis, drawing the liquid out of the meat cells. As that amount mixed in would make the food unpalatable, it is used on the surface of of large pieces - think ham. Curing salts work differently, they contain sodium nitrite and similar salts.
Spices as preservative
Spices do have some effect, but not to a degree to make ground meat stable. Note that excessive use of spices may aid in digestion, but even more was traditionally used to mask "off" (read: slightly spoiled) tastes and smells.
Vinegar as preservative
A very dangerous bacterium is Clostridium botulinum, causing botulism. It can be inhibited in low-ph environements. Yet two tablespoons of vinegar won't get you in a safe ph range.
Cooking to make food safe
While heat will kill most bacteria and molds, it will not necessarily kill the toxins produced by them before. (It does work for botulinum toxin, though.)

"Not safe" does not automatically mean "will make you sick". Those recommendations are based on statistics and include a safety margin. But if you or someone with a possibly weaker immune system does get sick, the consequences can be lethal.
