To get a guaranteed four-star sandwich you need to have all five different kinds of Herba Mystica on your sandwich. That means you need Sweet, Salty, Spicy, Sour, and Bitter Herba Mystica to be present when you begin. A player can only bring a max of four Herba Mystica at a time to any recipe, so communicate clearly to ensure you have all five unique named ingredients selected between your group before you begin cooking.
