Combine the yellow mustard, apple cider vinegar, golden Lakanto, sugar free honey, ketchup, and Worcestershire sauce together in a bowl.

Taste for seasoning - it may well already be perfect for you. But if you want to take it to the next level, add a chipotle pepper, and add them to the bowl with a little of the sauce as well. Add the second pepper and more sauce if desired. Finish with a grind of black pepper.

Transfer the sauce to a jar, then cover and store in the fridge. 

To reheat, place the required amount in a small saucepan and warm through. Alternatively the sauce can be reheated in the microwave.
