Using a stick blender (immersion blender), purée whole tomatoes. Add sea salt to taste and opt to add Sukrin Gold. Continue over low heat and stir regularly until sauce thickens, about 5 to 10 minutes.
Cool and transfer in an airtight container. Store in the refrigerator for 1 to 2 weeks.
The low carb brown sweetener (Sukrin Gold) helps enhance the flavor. A small amount of any low carb sweetener can be used as well.
