After years of juggling imprecise grilling recipes and temperatures, I've made a grilling calculator that derives perfect meat results from thermal models, Fick's law of diffusion, protein structures, and more.

Along the way I calculated exactly how far in advance to salt meat (spoiler: even when it's frozen!), realized the best dry brine is usually "cling brine" (covered), derived approximate charcoal quantities with physics, and much more.

As with the pancake calculator[1], I did an insane amount of grilling to develop this. And like the pancake one, it's a pure ESM library with frameworks around heat and salt diffusion and the other underpinnings, making it easier to develop more recipes.
