If you are lucky enough to find some of these delectable forest treats, then you need to clean them so you can eat them, and dry or freeze them. I think the most important rule is to keep everything dry.Introducing water makes a mess. Dry brushes are the best tools for the job. I picked my mushrooms in an old growth forest where I felt their surroundings were pretty pristine. That really helps to know they are free from pollution. The ones I picked were covered with fir needles, some dirt, and bits of this and that from the trees above. No bugs. Again, that helps to know they are ready to clean the rest of the way. I haven't seen bugs on Chantrelles, but I guess there cold be anything that might be in the woods anyway. So using a stiff painting brush, I start sweeping the debris away. If there is any convolution with dirt in it, I use the tip of my knife to flick it out. I can also use the side of the blade to scrape lightly if there is any tissue brown or damaged. As a last result, I can trim any of the mushroom off that isn't going to clean up.
