Ingredients :

• Beef or turkey sausages — The heart of the matter. Get real sausages with character—lightly smoked if you can find them—not those bland plastic mini-franks. The tastier the sausage is before cooking, the less you’ll need to adjust the sauce later.
• Canned white beans — No need to soak them overnight. A good can of white beans or cannellini does the trick perfectly. Rinse them quickly under cold water before adding—it removes the canning liquid which can make the sauce cloudy and too salty.
• Ketchup — Yes, real good-brand ketchup. It provides the sweet-and-tangy base for the sauce. Discount ketchup is often too sweet without any acidity—you’ll notice it in the final taste.
• Brown sugar — One tablespoon. It melts and lightly caramelizes the edges, giving that homemade BBQ sauce vibe that you just can’t replicate with ordinary white sugar.
