About
Corewise answers the only two questions a water bath really raises: when is the core at temperature, and when is it pasteurized. It does not look them up. It solves them. Give it the thickness, the shape, the starting temperature and the bath temperature, and it solves the heat equation inside that exact piece of food, then integrates pathogen lethality along the core temperature as the cook proceeds. That is why it can answer for a 47 mm rolled roast started from frozen, which no printed table covers. The part you actually look at is the Core View: a cross section of your food coloured by the solved temperature at every depth, from the cold core to the hot surface, with a scrubber under it. Drag through the cook and watch the heat arrive, with a marker on the timeline at the moment pasteurization completes. The colour scale is absolute, so 55 degrees looks the same in every cook you ever run. Shape matters more than most cooks expect, and it is where lookup tables quietly fail: a cylinder of the same thickness reaches temperature in about half a slab's time, and a sphere faster still. A frozen start is not a multiplier either, because the ice has to absorb its latent heat of fusion before anything else can happen, so Corewise solves that properly rather than guessing. The numbers follow Douglas Baldwin's published sous vide model with the USDA FSIS tables as a second reference, and the engine is checked against the analytic solution of the heat equation in its own test suite. There is no account, no analytics and no network request of any kind.
