- STEP 1
Heat the miso paste in a saucepan with 800ml water. Whisk to dissolve, then bring to a simmer. Add a little more water if needed.
- STEP 2
Mix the cornflour with 2 tsp water until smooth, then stir a little of the mixture into the miso. Let it bubble and thicken, stirring occasionally. If the gravy isn't thick enough, add an extra splash of the cornflour mixture.
- STEP 3
For extra richness, add the nut butter (if using) to the mixture and stir well. Season to taste, then serve.
