An Idea Scott had on Minecraft Forum to give the cauldron a purpose. Wanted someone to elaborate, I obliged.

I'm thinking enchanted food. Depending on the ingredients, you could cook chicken, add sugar and get the speed effect, or blaze powder for strength etc etc. The food could have a higher saturation level when cooked with roots.

So it could have a UI with 3 slots. 1 for the food item, one for roots, and one optional for the potion ingredient to give it the desired effect.

I'm also thinking that it should only be 1st tier effects (No glowstone/redstone powder to make it last longer/more potent) as to not replace brewing altogether.

The trick will be balance. We do not want Extrabiome to become the cauldron mod...

You know...the latest snapshot added Carrots and Potatoes, both common stew ingredients. Expanded cauldron functionality also appears to be in the works for the upcoming release. I think that Mojang may be beating you to the punch! XD

Good! (Less we have to write!)
