I have an idea for the cooking system for BOTW
When ever you cook a food item, it starts out with hot and cools down after a while, and heats up and cools faster in certain areas, it heats up slowly on heat level 1 in gerudo desert, and a bit faster on level 2, death mountain scorches the food and requires a certain pouch to prevent that from happening
Example

Frozen hearty mushroom skewer, provides a level 2 heat resistance, temporarily increases maximum life

Cold hearty mushroom skewer, provides a level 1 heat resistance and temporarily increases maximum life

Room temperature hearty mushroom skewer, temporarily increases maximum life

Warm hearty mushroom skewer, provides a level 1 cold resistance and temporarily increases maximum life

Piping hot hearty mushroom skewer, provides a level 2 cold resistance and temporarily increases maximum life

Scorched hearty mushroom skewer, tastes terrible, heals 2 hearts
