Puzzle 759 Witch's Kitchen

As the chef, on a sunny autumn day, you went to the forest to gather mushrooms. You have just found a unique mushroom that you carefully cut and placed in your basket. The mushroom looks quite appetizing. You can't help... but take a small bite. Suddenly, you feel dizzy and fall to the ground in front of a large old tree. You realize you have been poisoned and need a quick-acting remedy. Suddenly, the ground beneath you gives way, and you feel yourself falling. You wake up in a gloomy room that resembles a witch's kitchen.
Perhaps you will find the remedy here? Where could it be? How will you prepare it? Your time is running out...
