Later, cannellini beans would be soaked in water, then put to rest by the side of the fire in a fiasco (typically a glass bottle), containing water, rosemary, garlic, and olive oil, and left to cook very slowly overnight. The next day, vegetables would be harvested, cleaned, chopped, and added to the pot along with the soaked bread. The final, and probably most important, ingredient in this simple Tuscan dish is the drizzle of extra-virgin olive oil poured on top prior to serving.
