How to Make a Low Carb Smoky Barbecue Sauce
In a saucepan, mix together tomato sauce (from a can, not ketchup!), white wine vinegar, minced garlic (or garlic paste), dry mustard powder, paprika, and the key ingredient: liquid smoke. Liquid smoke is an all-natural flavor enhancer with no carbs, no additives, and no preservatives. It packs quite a punch and is perfect for making this sauce. You'll also need some sweetener - I love using classic Lakanto. But if you had some homemade simple syrup to hand - that would also work well!
Once you have the desired sweetness, bring the sauce to the boil and then reduce to a simmer for five minutes. Season with salt and black pepper to taste.
This is one of those sauces that will actually taste better the next day, so make it in advance if you can! Just store it (covered) in the fridge until required.

How would this be without the sweetener? I don't use sugar (of course) and I avoid artificial sweeteners as much as possible.
Georgina says
I haven't tried it but I think it would be more like a smoky tomato sauce. There are lots of natural sweeteners that aren't artificial these days - and many of them are zero carb!
