Why don't Critters or Monster Parts make Meals?
Although Tears of the Kingdom does allow you to cook with some seriously questionable items, Critters, and Monster Parts are grayed out and off-limits. This is because these items form the basis for elixirs, another type of consumable that can boost status effects in a myriad of different ways, separate from foods. Other than these items, though, everything else is cookable, so mix and match in as weird a way as you want and see what hidden gems you can find!
