The Vestals embody the profound connection between domestic cult and the religious life of the community. Any householder could rekindle their own household fire from Vesta's flame. The Vestals cared for the Lares and Penates of the state that were the equivalent of those enshrined in each home. Besides their own festival of Vestalia, they participated directly in the rites of Parilia, Parentalia and Fordicidia. Indirectly, they played a role in every official sacrifice; among their duties was the preparation of the mola salsa, the salted flour that was sprinkled on every sacrificial victim as part of its immolation.

Answer this question, if possible (if impossible, reply "unanswerable"): To what part of official state sacrifices did the Vestals attend?
