The secret to this sauce is ground bison, good fatty pork sausage, brown sugar and lots of red wine! Brown sugar adds a sweet addition that balances out all the flavors and acidity in the tomatoes and makes it a touch more savory. With any tomato sauce the flavors improve with time. Cooking it low and slow all day makes this spaghetti the best you've ever had! Place in the crock-pot for an all day simmer and fill your home with comforting Italian fragrance. Freeze the leftovers to create a starter for your next sauce and just keep adding to it every time you crave some good spaghetti.
