Witch's Kitchen

It’s a sunny autumn afternoon and you are looking for mushrooms in the forest. When you find a particularly delicious-looking specimen, you are unable to resist and try a bite. You begin to feel dizzy and you fall to the ground. You realize that you have poisoned yourself and need to find the remedy! Suddenly, the ground caves in and upon regaining consciousness you find yourself in an underground room that appears to be a witch's kitchen.

Can you find the remedy to save your life?
