The oven allows you to cook certain foods as you would with a furnace but without the use of coal. The foods you can cook are:
- -Raw steak
- -Raw porkchops
- -Raw chicken
- -Raw fish
- -Raw salmon
- -Flesh (obtained by freezing rotten flesh with a freezer)
To use the oven, place any of the previously mentioned raw foods into the top row of the oven and the oven should turn on automatically. Once the food is done cooking, it will appear in the bottom row as it's cooked version.
For more information, seek the "Recipe Book" in-game by going into creative mode to view MrCrayfish's furniture mod tab in the creative mode inventory. It's a blue book that when opened, tells you all of the crafting recipes and uses for each appliance.
You can also obtain the Recipe Book by purchasing it from "MineBay" on a computer with one emerald.
