I know you said you weren't looking for a prepackaged mix. We go to the local meat market and buy there summer sausage mix and add the extra garlic and other flavors that we like. They have it mixed for 25 pound batches that is a nice size for us to use. Unless you are making a lot it is cost efficient because you don't need to buy a of bunch different spices that you may only use for summer sausage.
