Atomic, the spices you use sound interesting. Meat Confit predates refrigeration, canning and even Cure by many years. The salt and cooking at 225°F is effective at killing Clostridum Botulinum spores, although I can see the addition of Cure #1 and even Cold Smoking a few hours, before processing, would make a tasty product.
Dave, I have tried the Packed in salt method and found it made a way too salty end result. The recipe I use is very similar to this...
http://www.epicurious.com/recipes/food/views/duck-confit-102313 sans Shallots. The meat is falling off the bone and moist from the collagen and fat with very little of what I would call Juice, think FOB Ribs. Some juices, as Atomic describes, can be found in the pan and gelatinize when cold.
This would be in your wheelhouse...Olive Oil Confit of Garlic is out of this world delicious. The garlic gets tender and sweet and the flavored Oil is great for cooking. We Confit peeled cloves, from 10 heads, 325°F covered with EVOO until golden and soft. We then mash them hot with some Raw EVOO, real Parm Reggiano Cheese and a pinch of salt and Red Pepper Flakes. Spread the paste on crusty bread as an appetizer or as part of a meal with Wine, Cheese and Olives, maybe with some Coppa or Prosciutto. The amount of Duck Fat needed can be pricey with shipping to get started but the more you use it, the better it gets and becomes self replenishing. These guys have some good prices...
