Put everything into a medium heavy-bottomed pot and bring to a very gentle boil over medium heat, whisking constantly.

Let the mixture simmer for 3-5 minutes over low heat; be careful not to let the mixture scorch the bottom of the pot.

Taste and adjust seasonings according to personal preference.

Take the pot off the heat and use on satays/stir fries/etc, or let the sauce cool down to room temperature for later use.
