In a small saucepan, add all your ingredients and mix until combined.
On medium heat, warm up the saucepan and its contents. Once it begins to simmer, reduce the heat to low and stir constantly for 5 minutes. Taste the sauce and add either more sweetener or more salt, depending on taste.
Remove the saucepan from the heat and let cool completely.
