The Sisters of Sarenhag

From BoardGameGeek:

Sisters of Sarenhag is an adrenaline-rushed potion brewing game where players attempt to brew the most potent potions, while sabotaging their opponents' potions. The game takes place over three rounds with three phases each. The Brewing Phase, where players are adding ingredients and casting incantations into cauldron in real time; the Bottling Phase, where players try to sell their potions, without exploding, for money; and the Sweeping Phase, where players prepare for the following round by cleaning-up their ingredients. At the end of the third round, players will determine who is the best witch around! -description from the designer
