The ancient recipe of red yeast rice

To create red rice, find a place with red soil and dig a deep pit. Surround the pit with bamboo mats and pour in japonica rice. Press heavy stones on top to facilitate fermentation and the development of the rice's distinctive red coloring. After three to four years, the rice will have a purple-red outer skin and a red interior. Be sure to avoid rice with white spots for the best quality.

In the Compendium, a modern method for creating red yeast rice is described. Using one stone and 5 buckets of white japonica rice, the process involves piling and covering the rice with silk, creating multiple piles over a period of several days. Fresh water and bamboo baskets are used to complete the final stages of processing, resulting in bright red and lovely rice. When used for medicinal purposes, long-term use is recommended for optimal results. Overall, the method is considered a form of thaumaturgy and requires attention to detail and patience to achieve the desired outcome.
