Protein cookery can be divided into two categories: dry-heat and moist-heat. Moist-heat cookery encompasses poaching, braising, boiling, steaming, and the like, as well as sous vide techniques where a water-based solution is added to the protein before vacuum packing. These are usually done at lower temperatures–obviously these processes cannot exceed 212 Fahrenheit, except for steaming, which is actually gentler than boiling (because of the lessened density of the cooking medium).
