Root Beer Peanut Butter BBQ Ribs

These were perhaps the best ribs I've ever tasted, very sweet and spicy. I essentially made up the recipe, and no one will guess the secret ingredients if you make it. Here it goes:

First, make a dry rub and rub it over about 750g (1.5 lb) of ribs (2 sets):

• 1 tbsp cayenne pepper
• 1 tbsp Cajun seasoning
• 2 tbsp brown sugar
• 1 tsp ground ginger
  
• bit of salt

Let that sit for about a day in the fridge. Then make the bbq sauce out of the following (I'm trying to remember what I put in):

• 3 cups of root beer, boiled down to 1 cup
• 2 1/2 tbsp Worcestershire sauce
• 1 1/2 tbsp lemon juice (from the bottle)
• 2 tbsp brown sugar
• 2 1/2 tbsp peanut butter (much better than ketchup!)
  
• 1 tsp liquid smoke
• 1 tbsp spicy chicken wing sauce
• 1/2 to 1 tbsp cayenne pepper
• 1 tsp soy sauce
• 2 tbsp cider vinegar (great for the pork!)
  
• 1 clove minced garlic
• 1 tbsp maple syrup
• 2 tbsp dijon mustard
• 1/2 tbsp hickory bbq sauce (all I had left)
• 1/2 tsp ground ginger
  

I think that covers every reasonable sauce I could find in my fridge and cupboard. Then boil all those for about 15 minutes, stirring pretty often. You should end up with about 1 1/2 cups of sauce. Pour 1/3 the sauce in the slow cooker (Crockpot) and then put in the first set of ribs, then pour more sauce over them, then the second set, then the rest of the sauce. Cook that on low for about 6.5 hours. Then gobble them up.
