On stoves in restaurants and portable stoves you can cook some nice meals now. As ingredients you need vegetables from farming, flesh from monsters or fishes from the sea. You can make items that give more food points, and they are more valuable so you can make more money with farming now. If you want to make food at your (virtual) home, just craft a house cooker furniture, place it in your house and grab it to see the menu of food items you can cook.
