The Widow Caravelli

The Widow Caravelli was a woman in Sophia's village, located in Sicily. According to Sophia, any illness you had, she had a cure. The widow gave "Salvadore the Village Idiot" ear salve for his current infection. Salvadore accidentally used it on his pasta, which shockingly tasted good. Salvadore apparently changed the name of the salve to pesto sauce, and the spaghetti and ear salve flew like a hit.
