Applegate Farms brand since they have no added nitrites or nitrates. I think any kind of smoked sausage would work fine or whatever healthier option you prefer. We almost never eat this type of meat so I went with a low-sodium smoked turkey sausage. I am, however, holding on to an Andrew Zimmerman Borscht recipe but it takes 4 hours. BUT it has short ribs instead of polish sausage so I'd say it's worth the time. I'll probably try that one for my Russian Olympic dinner.
