Add all the ingredients except water to a saucepan and whisk until combined.
Cook over medium heat and bring to a simmer, stirring frequently.
Reduce the heat to low and cook, stirring often so it doesn’t scorch, for 2-3 minutes.
Add water and cook for another minute.
Add some more warm water if you want a thinner sauce.
Remove the pan from the heat and let the sauce cool slightly.
Transfer it to a container or jar, cover it, and keep it in the refrigerator for up to 2 weeks. Use as desired.
