Jen Billock, a Chicago-based travel writer and self-proclaimed "Cheese Witch," uses cheese to predict the future using a practice known as tyromancy, which dates back to the second century and was used in medieval England to determine criminal guilt and harvest seasons. The process involves four pieces of cheese selected by the client, which are then used to provide a specific reading. The type of cheese can affect the signal, with blue cheese being particularly noisy and more clean. Billock also reads tarot, rune stones, wedge salads, croissants, beer, wine, and curry.
