Storage
Keep chestnut mushrooms in the fridge. They retain their quality best at a temperature of between 4° and 7°C. They will then keep for 7 days.

It is best to leave the chestnut mushrooms in the packaging in which they were packed. If they are loose, do not put them in a sealed plastic bag. This suffocates the chestnut mushrooms, making them moist and unsightly. Chestnut mushrooms need to 'breathe', in a paper bag or a dry tea towel will do.

Do not store chestnut mushrooms with strong-smelling vegetables, such as leeks and onions. Chestnut mushrooms easily pick up odours. Do not store them with fruit either, as they will deteriorate faster.

How can I tell if chestnut mushrooms are no longer good? Chestnut mushrooms are mouldy, limp or have a sour smell. You can quickly recognise decay by looking, smelling or even tasting.

Preparation
Slice or quarter the mushrooms and leave the stalk on.

Cleaning chestnut mushrooms

Wipe the chestnut mushrooms clean with a kitchen paper or mushroom brush. Do this only just before cooking.

You clean chestnut mushrooms dry. Do not wash them, as they will fill up with water and lose their flavour.
