When cooking sous vide, what is the primary food safety concern with holding proteins below 130°F (54.4°C) for extended periods?
Answer: Growth of Clostridium botulinum and other pathogens in the anaerobic environment
Below 130°F, pathogens like C. botulinum can multiply in the anaerobic vacuum-sealed environment, so extended cooking must stay at or above this threshold.
In a classic liaison used to finish a velouté, what is the correct ratio and procedure?
