Great looking kielbasa!
Isn't it great to have fun doing something like this and have the reward of getting to eat something delicious as a result?
Good old-fashioned polish kielbasa has a few basic essentials: meat (traditionally pork), salt, pepper, garlic & optionally, marjoram. Add cure if smoked.
The SPC or NFDM would be used if one is using a combination of meats.
