Hints and tips
- Yuzu koshõ can be purchased from Asian grocers.
- If making your own yuzu koshõ, let it sit for a couple of days before using, for a deeper flavour. It can be stored in the refrigerator for up to two weeks.
- If fresh shiitake mushrooms are not available, use rehydrated dried shiitake. Do not discard mushroom liquid. This can be saved and used in stocks or soups for extra flavour.
- Using the sous-vide function to cook the pumpkin concentrates its flavours and retains the beautiful colour.
- Butternut pumpkin can be substituted with other varieties such as jap or kent if butternut is not available.
