We brew the potion together, following every direction and taking turns. The only thing we have to add is the stewed Mandrake. Before opening the jar I shake it once again, just to be sure it will increase the potency of it. I uncork it and a sour smell lifts from the bottle, making my stomach turn. I have only a second to figure out my next step. Instead of vomiting all over the floor, I bend over the cauldron and expel everything I ate in the last day from my body. The oder even worse than the stupid Mandrakes.
