How to clean mushrooms?

Once we have discovered that the mushrooms we have picked are edible (if you have doubts, it is best not to do so to avoid greater harm to your health), it is advisable to clean them properly before cooking.

Contrary to what you might think, it is not a good idea to rinse them under running water, or even leave them to soak, since this will only help them to lose flavor after preparation in the kitchen.

The best option to clean them is to use a knife, cutting the tip and scraping it to eliminate the different remains of soil and substrate that we can find on them.

When it comes to checking whether or not they have larvae, the best thing to do is to cut the hats, which is the tastiest part and where they tend to stay.

It is also advisable to check if the mushrooms are in good condition. This will be indicated by both its color and its aroma: the color, for example, must be the characteristic color depending on the variety (chanterelle mushrooms or chanterelles tend to be orange in color), while the aroma is fruity.

And how can we best preserve mushrooms at home?

When it comes to preserving mushrooms there are three ways that allow us to keep them until they are consumed, especially to prevent them from going bad. Of course, once you clean it, you can choose between these three options:

  • In a saucepan with boiling water, let them stand for two minutes to bring them to a boil.  Add olive oil to sterilized jars and keep them in them.
  • In airtight bags, you can freeze them to maintain their virtues.
  • Let them dry. To do this, you just need to string them on a thread and put them in a dry but airy place.
