This week on Fuhmentaboudit!, Mary, Chris and Rachel are joined by Rich Shih, a mechanical engineer by trade whose passion is kitchen experimentation. When a friend suggested he work with koji, he became interested in playing around with miso flavors. Rich also founded Our Cook Quest, which provides "informative and fun" cooking classes, in-depth analyses, and investigations of cooking techniques to improve and inform culinary adventurers. Some of Rich's unusual misos include peanut butter, ricotta, bacon, and cookie dough.
