Baking hot oceans and land requires animal meat, Heraru perch and warm grass fruit. Warm tsaoko can be found in grandpa's small room, or at the entrance of the snow-capped mountain on the west side of the ruins of the Temple of Time. Hunting wild boar in the Woods north of the initial map can get animal meat, and Heralu perch can be caught in the pool near the initial tower. If you don't have enough strength to swim, you can stand on the shore and fry fish with the skill of stone card.
After all the items are collected, you can go back to grandpa's hut and choose to put three materials, namely animal meat, Heralu perch and warm grass fruit, next to the pot to make a hot sea-land fried roast. You can get cold clothes by telling grandpa after cooking the land and sea.
