Place all ingredients in a small saucepan over a medium heat. Stir intermittently for around 10-15 minutes, or until it has thickened. Add some freshly cracked pepper and use in whatever you're doing (bolognese obviously encouraged.) Store in an airtight container and use within a week or two.
This yields a small quantity, perfect for a single batch cook (around 4-5 tablespoons.) This is the amount necessary for my vegan bolognese, but obviously double the quantities if you need a larger volume.
