I also agree on the BBQ sauce, it's not the same.
This is a nice recipe from scratch, granted you can find the liquid smoke. P.S. Mods, if you feel this reply is in the wrong topic, feel free to move. It won't hurt my feel-bads.
1 c. tomato passata
4 c. Heinz ketchup
1/2c. cider vinegar
1/2c. margarine or butter
1 c. water
1 t. liquid smoke
1 c. treacle (my original recipe calls for molasses)
2 t. hot sauce (I would substitute peri peri)
1 t. garlic powder
1 t. onion powder
1 T. demarara sugar
1/2 c. HP brown sauce (original recipe calls for A-1)
2 T. seasoned salt
1 c. Pepsi or Coke
1/4 c. dark soy sauce (Amoy is my fave)
1 t. red pepper (flakes or ground), optional
Combine all ingredients in saucepan; mix well and bring to a boil stirring constantly to avoid scorching. Reduce heat and simmer 1 hour stirring occasionally.
(Yield: 2 quarts)
