The Winter's Feast masonry oven, along with the table and the new foods are very interesting mechanics. Although the buffs the food give you aren't too useful, and the methods of crafting them are a bit too convoluted, I think a permanent version of these mechanics would make for fine permanent additions to the game. Since the Gorge event, many have yearned for more in depth farming and cooking systems. The holiday additions give us a nice taste of what could potentially come.
Personally, I'd like to see them keep a mechanic like this in game. It is perfectly on brand for the game (magical oven that produces magical food). Maybe it'd be a boss-drop exclusive oven? For example, a dragonfly scale, 10 nightmare fuel and a red gem would be used to produce a special dish that provides warmth for x amount of days, depending on how much of it you eat. There could be speed dishes, max health dishes, armor resist dishes, and many more. It'd make for a very useful late-game playstyle. What does everybody think about the new Winter's Feast cooking and foods?
