I think a cooking minigame with the purpose of bulk cooking (similar idea to blast furnace for smelting bulk bars) would be appropriate. Its killer after spending a weekend doing minnows or fishing karambwan just spending hours on hours to cook stuff you already spent hours on hours getting.
Maybe a base concept would be something like having an oven you heat up with different logs that keep it going for different time based on quality. Then you load the conveyor belt with your uncooked food and collect on other side. Maybe could also have potential to have some unlockable rewards you can get for it like minor reduced burn rate or auto disposal of burned food.
Maybe with this method to keep it balanced would be reduced xp for each food to keep traditional styles relevant as cooking doesn't need any faster xp methods. Just primarily for quicker bulk cooking so you can get onto more enjoyable things 🙂
