As it is right now, making tea in any amount larger than one pot is a massive pain.
I propose therefore that instead of making tea as we do now, with a crafting recipe, rather one of two things could be done instead:
1. simply adding tea leaves to the cauldron's inventory and waiting for the water in the cauldron to turn to tea over time, perhaps having a required minimum of leaves dependent upon the amount of water in the cauldron.
2. Having us be able to hang teapots from roasting spits over fireplaces, increasing the amount of liquid a teapot can hold, and giving it some sort of inventory for the leaves, and let the tea brew passively over time, in larger amounts to compensate for the wait compared to the current method.
Personally I think either would be superior compared to how it works now.
