There was a little joking going on in Madhur Hathur about muffins and cupcakes, which spawned a brilliant idea of: why isn't there some type of oven to bake foods? Like an EZBake oven, it can built out of metal or what not and a light bulb. Or heck even to build an actual oven for houses or tower like other machines. This could make new skills, new quests, new foods, etc. There could be a plethora of ideas. For example, cupcakes and muffins (cloudberry or whortleberry, or any berry/fruit really) they can be made out of flour, milk, butter, honey or syrup, fruit, the list could go on. Or things like lasagna, we already make pasta and bolognese sauce, just had some extras like meat or veggies and cheese. Or even salmon casserole, spin on tuna, cause right now salmon is only really used for cedar plank dish. The ideas could essentially be endless and easy to incorporate with what is already in the game.
Just food for thought, no pun intended. :D
