Sweet and Smokey BBQ Sauce and ribs

The husband asked for ribs tonight, so I came up with a recipe after looking at a few different ones to come up with the flavors I like. Here goes:

1/2 cup ketchup
tiny can of tomato paste
1/2 cup brown sugar
1/4 cup apple cider vinegar
4 tbls molasses
1 teas hickory liquid smoke
1 teas Worcestershire sauce
2 tblsp melted butter
1/2 tsp garlic powder
1/2 tsp onion salt
1/4 chili powder
1/4 smoked paprika
1/4 celery seed
1/4 cinnamon
cayenne pepper for heat
a decent amount of freshly ground black pepper

I mix it all up with an immersion blender and it is good to go.

For the ribs I boiled them in water with some soy sauce and garlic powder for 45 minutes. Then I put them in the oven at 325 with 1/2 the sauce for an hour covered in tinfoil. After the hour I take the tinfoil off and add 1/2 of the remaining sauce and cook for a half hour. When done I let them sit for a few minutes to settle then you have extra sauce left over for dipping.
I usually get a full rack of ribs cut in half (so ~12 per half) so they fit in the pot and in the oven better. You can grill these on a low heat after the parboil as well.
