Cook My Meat: heat diffusion through meat over time
This simulation shows the heat transfer throughout various kinds of meat. In the first section, you can input the starting values for the meat. The default is a 3cm piece of steak at room temperature (73°F or 23°C). The maximum meat thickness is 30 cm since we are assuming you're not trying to cook a whole cow. The…
