Add the shortribs in a single layer in a large baking pan.
Sprinkle the thyme, salt, pepper and paprika over the ribs.
Pour the Worcestershire sauce and beer over the ribs.
Cover the pan tightly with aluminum foil.
Bake for 2 1/2 hours.
While the ribs are baking, make the BBQ Sauce:
Add all the sauce ingredients into a 2 quart pot. Stir thoroughly to incorporate all ingredients and cook over medium high heat. Bring to a boil. Reduce heat to medium low and simmer for 30 minutes or until sauce thickens.Note: The beer will begin to froth when it boils - stir rigorously.
Turn off the heat and set aside.
2 1/2 hours later:
Remove the ribs from the oven. Carefully remove the cover.
Pour the BBQ Sauce over the ribs. Return to the oven, uncovered, and bake for 30 minutes.Note: The meat will be very tender and some of the bones may likely fall off the meat.
Remove the pan from the oven. Tranfer the ribs only to a serving bowl.
Pour all of the Beer BBQ Sauce into a 2 quart pot. Bring to a boil over high heat. Cook until sauce is reduced to half and thickens. 10 to 15 minutes.
You can use boneless short ribs if preferred.The BBQ sauce has a tangy taste. If you prefer a little sweeter sauce, use 1/3 cup brown sugar.You can also use either beef or chicken broth instead of beer.
