Oyster mushrooms contain a lot of vitamins and minerals: B, C, D, K, magnesium, potassium, phosphorus, chromium, copper, zinc, iron, selenium, as well as fatty acids and even fibre.
Their composition help in normalising cholesterol levels.
Oyster mushrooms can be grown indoors. You can buy bags with a substrate from which the mushrooms can be harvested gradually, or you can buy a dedicated log for the purpose - although the process will be a bit slower.
The mushrooms need appropriate conditions, which will vary from stage to stage. At first, they need 20 to 25°C, and for the next phase, a temperature of about 10 to 15°C is sufficient.
Both body and stem are harvested; they feel hard, but will soften as you cook. They are also great in powder or capsule forms.
