Drying mushrooms in the oven

We will need a grill for the oven. Mushrooms need to be cut so that they do not fall through the grate. Preheat the oven to 50-60C.
You can put a smaller one on top of the standard oven grill (buy extra), then the mushrooms can be chopped and finely. Boroviki, for example, I cut into plates, but I don't cut honey mushrooms at all. If you lay paper on a baking sheet, then you can install double drying: a grid on top, a baking sheet on the bottom.
The oven should be kept slightly ajar - so the evaporated moisture will come out. Depending on the mushrooms, it will take a little more or less time. Dry for 2-3 hours, then close the oven and dry for another 4-5 hours at 50C.
Mushrooms should not be kept and washed in water before drying! Try to clean them dry using a stiff brush. If your oven has a "vent heating" function, turn it on.
