Wow! Sounds interesting!@Dahlia, not everyone would try this but it is very tasty .
"Saute some onions. Add rhubarb, a can of Dr. Pepper, a cup of apple cider vinegar, about a cup of brown sugar, maybe some molasses, and a tablespoon of Worcestershire sauce. Smoked paprika, garlic salt, several grinds of black pepper ... dash of cinnamon, a sprinkle of allspice and cloves.
Cook on top the stove until the rhubarb is soft and bubbling sauce is making the constant stirring a little dangerous . Run through blender but be careful if it's very hot! Barbecue Sauce!"
