Mushroom Miso Butter Recipe

Mushroom miso butter will be the undoing of me. Super quick to make, your fridge should never be without it, ready to be spooned into a fluffy just-baked potato, stirred through some cooked noodles or steamed rice, or used to sauté some green vegetables as a simple side of veg. You could also use it generously, leaving a chunk to melt obligingly onto a piece of grilled fish or meat or all barbecued vegetables, goodness, it’s even great slathered in a jazzy grilled sandwich or stirred through a
soup to serve. This recipe will have you asking yourself, what doesn’t go well with miso butter?

This keeps well in the fridge, for at least a couple of weeks, but you could halve the recipe if you are worried about butter consumption! You have been warned.

Ingredients for the Mushroom Miso Butter

  • 30g dried porcini mushrooms or dried wild mushrooms
  • 1 large shallot, very finely diced
  • 75ml white wine or cider vinegar
  • 2 tablespoons red miso (although white is also fine)
  • 200g butter, softened
  • salt and freshly ground black pepper (optional)

How to make Mushroom Miso Butter

  1. Add the dried mushrooms to a heatproof bowl, pour over 75ml (3fl oz) of boiling water and leave to soak for about 10 minutes until soft. Once softened, remove the mushrooms and finely chop, reserving the soaking liquid.
  2. Bring the shallot, chopped mushrooms and vinegar to a boil in a small saucepan over a moderate heat and simmer vigorously until all the liquid has evaporated and only the shallot and mushrooms remain in the saucepan. Add the reserved mushroom soaking liquid, leaving any sediment behind, and simmer vigorously until all the liquid has evaporated. Allow to cool completely.
  3. Beat the miso and shallot and mushroom mixture into the butter and add a good grind of salt and black pepper to taste, if required, and if you used unsalted butter. Roll the mixture into a cylinder using greaseproof paper to shape and wrap it.
  4. Store your mushroom miso butter in the fridge (it will keep for a couple of weeks) and slice to use.
