How to rehydrate dried mushrooms

How to rehydrate dried mushrooms
Rehydrating dried mushrooms restoes them to something like their fresh texture, ready to use in a recipe.

You will see that there is more to it than simply leaving them to soak in water. At the same time, we can also make a delicious mushroom "jus" to use in recipes.

Throughout the recipe, I have used morels as the example, but the same applies to any other dried mushrooms.

Step by step recipe

Stage 1 - 1 min.
How to rehydrate dried mushrooms
Take 50 g dried morels out of the packet.

Stage 2 - 30 min.
How to rehydrate dried mushrooms
Put them in a bowl and cover with hot water (not boiling).

There should be about 1/2 an inch (1 cm) between the floating mushroms and the bottom of the bowl.

Cover and leave to soak for half an hour.

Stage 3 - 3 min.
How to rehydrate dried mushrooms
After this time, remove the mushrooms carefully from the water with a skimmer or, better still, an "araignée" (spider). It is important not to tip the mushrooms out with the water as this is usually full of earth or sand and you will dirty the mushrooms again. So, the mushrooms need to be lifted cleanly out of the water.

Set aside the soaking water for later.

Stage 4 - 30 min.
How to rehydrate dried mushrooms
If you are using morels, which tend to be full of dirt (and only in this case) put them in a fresh bowl of hot water and leave to soak again for half an hour.

For other mushrooms, one soaking is enough.

Stage 5 - 3 min.
How to rehydrate dried mushrooms
Meanwhile, go back to the soaking water which is much too good to throw away. It has been transformed by absorbing the flavour of the mushrooms and is now a very flavoursome mushroom "jus".

Scoop out this "jus" with a ladle, being careful not to tip or stir up the water. Collect as much as you can that is "clear", without any dirt or sediment.

Stage 6
How to rehydrate dried mushrooms
Keep the mushroom "jus" in a sealed container in the fridge, but for a few days at most.

It can be used in any savoury recipe that asks for a flavoured liquid, such as stock (like morel risotto with vin jaune and mont d'or).

Stage 7 - 3 min.
How to rehydrate dried mushrooms
The final thing to do with the mushrooms is to drain them thoroughly before using. The best way of doing this is to use a salad spinner. Once drained, your rehydrated mushrooms are ready for use.
With morels, the proportion of dried mushrooms to rehydrated is 1:3. In other words, 50 g of dried morels will give you three times that weight when reyhdrated: 150 g.
A few days in the fridge, covered with plastic film.
Home made.
