Bubbling Cauldrons

When you put fire (campfires work too!) under a cauldron it will turn into a bubbling cauldron. In witch huts they'll use it on occasion to brew, showing you how it's done. This would make for cool new decoration and a fun detail for these small structures.

You can sometimes find witches brewing in swamp huts!

How do you brew with a cauldron?

Well, it's surprisingly simple. First once you get the cauldron full of water and boiling you can right click to add ingredients (There could be alternate recipes, allowing you to brew without netherwart, but that's a different topic I won't get into here). Stir, add the rest of the ingredients, mix it up and then you'll have 3 potions ready to go!

Cauldrons aren't as automatic as brewing stands, and won't just disable the adding of items that are aren't part of the current recipe, but will give green particles upon adding good items and angry particles when you add the wrong items. The cauldron water will likely change colours as it goes through the steps. After each ingredient you'll have to use a stick to stir it a bit, to give the player more of a feeling of interaction [note, cauldrons are not supposed to replace auto brewing/brewing stands, mostly give a new, fun, and interactive way to brew].

side note, perhaps the cauldron could make stews as well, but the mechanics would differ depending on the first ingredient you add, so a potion ingredient to start brewing, or a food thing to start cooking

Bonus details to witch huts:

Witches may not have every recipe remembered either! So perhaps you could find recipe notes of what ingredients are needed a random potion, rather than just be given all of them in a recipe book and remove any need to experiment or explore. As well the notes might even make for a neat little decoration!

The bubbling cauldrons in the huts perhaps could be found in different spots, or even nearby, giving a bit of a personal touch by each of the witches to make them feel a little distinct.
