BBQ sauce

• 2 cups ketchup
• 1/2 cup white vinegar
• 1/2 cup molasses
• 1 tsp salt
• 1/2 tsp allspice
• 1 tsp chile powder
• 1 tsp paprika
• 1/2 tsp hot sauce (e.g. Tobasco)
• 1/4 - 1/2 cup (depending on your propensity for sweetness) brown sugar 
• 1/2 tsp nutmeg
• 1 - 2 tsp ground cumin
• 1/4 tsp white pepper

Cook gently over a medium heat until you get a good thick consistency; typically around 30 minutes but best not to leave it unattended.
