Add the tomato paste, apple cider vinegar, brown sugar substitute, liquid smoke, smoked paprika, onion powder, garlic powder, salt, and water to a small saucepan and mix well.
On medium heat, heat up the saucepan until it begins to simmer. Once it simmers, reduce the heat to very low and stir for 4-5 minutes.
Remove from the heat and let cool completely to thicken.

TO STORE: Barbecue sauce must always be stored in the refrigerator, in a sealed container or jar. It will remain fresh for up to 2 weeks. TO FREEZE: Place leftover sauce in a freezer friendly container and store in the freezer for up to 2 months. Recipe variations
Make it spicy. For a spicy kick, add some cayenne pepper or red pepper flakes. Alternatively, you can even stir through some hot or buffalo sauce after it thickens.
Enhance the flavor. While optional, sometimes I like to stir in yellow mustard or lemon juice for extra flavor.
