This would be an oven that spawns in the Bakeries of the Beornings and of Dale.
Why? Because, Gimli describes the Beornings as
|“||The best bakers I know!||”|
–Gimli, on discussing lembas with the Elves of Lórien
and, the Dalish currently have bakeries but nothing to cook in!
It would have 6-9 slots, and be used in the making of cram (which would now have to be baked, and would give higher saturation) and in the making of the Beorning Honeycakes.
It would cook food just as fast as a Hobbit oven, but it would be more fuel efficient due to Men being more technologically advanced then Hobbits.
It would be crafted out of Dalish or Beorning bricks in the default forge recipe.
