Best Baby Back Pork Ribs

I make some really mean baby back ribs.
Just before winter I bought a new meat smoker
I can't wait to try out some new recipes in it.

Ingredients:
1 cup water
1 cup red wine vinegar
1/2 cup tomato paste
1 tbsp yellow mustard
2/3 cup dark brown sugar, packed
1 tspn hickory flavoring liquid smoke
1 tspn salt
1/2 tspn onion powder
1/2 tspn garlic powder
1/2 tspn smoked paprika

Dirctions:
Make the barbecue sauce by combining all
of the ingredients for the sauce
in a medium saucepan over medium heat
When it comes to a boil,
reduce heat and simmer sauce,
stirring often,
for 45 to 60 minutes or
until sauce is thick.

When you're ready to make the ribs,
preheat the oven to 300°F.
Brush sauce over the entire
surface of each rack of ribs.
Wrap each rack tightly in aluminum foil
and arrange the packets on a baking sheet
with the seam of the foil facing up.
Bake for 2 to 3 hours or until
the meat on the ribs has pulled back
from the cut ends of the bones by about 1/2".
When the ribs are just about done,
preheat your barbecue grill to medium heat.
Remove the ribs from the foil,
and grill them on the barbecue
for 4 to 8 minutes per side
or until the surface of the ribs
is beginning to charred.
Brush sauce on both sides of the ribs
a few minutes before
you remove them from the grill.
Just be sure not to brush on
the sauce too soon or it could burn.
Serve the ribs with extra sauce
on the side and lots of napkins.
