- Dried mushrooms covered with 300 ml just-boiled water, 15 minutes. Lift, squeeze, slice, keep the liquid minus the gritty base.
- Sesame toasted dry, out.
- Pasta on. Keep a mugful of the water.
- Oil, garlic and chilli twenty seconds, sliced mushrooms two minutes, then 100 ml of the mushroom liquid reduced by half.
- Off the heat, miso stirred in until it disappears.
- Drained pasta through it, loosened with pasta water until glossy. Sesame and pepper over.
Never boil miso. It is a live ferment and boiling flattens it to plain salt, which is the whole reason it is in the cupboard rather than more stock cubes.
