Inspired by the Hoisin Sauce recipe in Thane Prince’s Perfect Preserves
The sauce will keep for about 6 months if stored somewhere dark and cool.
*To sterilise the jars place the very clean jars you would like to use in an oven pre-heated to 140°C for 20 minutes. Sterilise the lids by dropping them into a saucepan of boiling water for 10 minutes with a splash of vinegar. I don’t sterilise my lids in the oven as they tend to ruin.
