Yes, measure by the fluid oz. I use medicine cups from the hospital. A baby bottle works good too. It is just the way we came up with the measurements. I have never really sat down and tried to convert it to tbs or tsp measures.
As to the 1 tablespoon per pound of meat - OK a generous tablespoon.
You guys should really try this recipe. Mix up a small batch of seasoning and get a lb of ground pork, from the store, and pan fry a couple of patties of this. You can also replace the accent with salt without any change in the flavor. It is great as a fresh sausage but shines as a smoked sausage.
