Thanks for all the nice comments, everybody!

I'll reply with a live-update; I just came back from a walk in the woods. I gathered some mushroom and a little of blueberries. I lit up the stove, preparing to boil potatoes. When I was about to start slicing the mushroom I noticed that there is someone on my yard. I went out and saw an elder fisher lady from the neighborhood. She brought me a pike-perch she had caught today in the morning. Thank You! I cut the fish to two fillets, then went indoors to write this comment. Now off to fry the fish together with the mushroom!
