I cook two traditional Brazilian dishes, carne loca and feijoada. In the past I prepared both of these, chuck roll for the carne loca and beans for the feijoada in a stove top pressure cooker. I have a 3 day event in August for which I will be preparing both for approximately 1500 people. While applying for my health permit in Orange County CA, I learned that my stove top pressure cooker was not NSF listed. To my surprise, when I tried to locate an NSF listed pressure cooker, a requirement of the Public Health office, I was unable to find any. The only one that I did find, Iwatani PC-135, was discontinued in December of 2016. The prospect of baking the chuck roll in an oven and the beans on a stove top pot drastically increases my prep time by many hours. Does anyone know of a manufacturer of NSF listed stove top pressure cookers? If not, can anyone recommend a process for cooking chuck roll or beans in an expedited manner? Any suggestions are greatly appreciated.
