Check your fridge and throw any leftover barbecued meat into the pot as well, especially the burnt ends of brisket, then simmer for a good long time. Regular maple syrup will do just fine here - or you can smoke it, as we do. The beans will need to soak overnight, and the pork belly needs to cure in a spice mix overnight, so start preparing these the day before.
This dish is quite sweet. We recommend reducing the amount of sugar if you prefer a more savoury result.
