Willow placed the troll blubber in her cauldron and lit a fire underneath it. She then took the bicorn horn and began crushing it with the mortar and pestle adding the crushed dust when the blubber had the consistency of water. She could start to see the solution begin to turn into a liquid solution. She put her nose to the cauldron to see if she could smell the sweet scent the professor said would happen. She gave a slight smile at the scent and thought "I can't wait to try this potion, if the smell is any indication of the taste it's worth becoming larger for."
