Hi, I'm the developer of the Tea Kettle mod, which is similar to Simply Tea, but with a more immersive and hands-on approach. It even has compatibility with Simply Tea, so their tea can be brewed with my mod's mechanics!

The Issue

Recently, someone submitted a-soulspark/TeaKettle#15 relating how Fireweed Tea couldn't be brewed with Tea Kettle, so I fixed it. The problem is, you still couldn't sweeten Fireweed Tea without a recipe.

The Real Issue

The problem is, although I could add the recipe myself and thus craft the sweetened cup, it would grant no bonus effects: the tea's level remained the same.

The Solution

Didn't manage to clone your repository, so here's a possible fix: when adding Fireweed Tea here, use a TeaDrink instead of Food.
It checks if tea is sweetened, and boosts the tea's effects if so. I'm not sure if that would cause any trouble, might want to ask KnightMiner about it.
For it to be craftable, here's the recipe I used, a simplytea:shapeless_honey-type recipe. Just drop it into your recipes folder and you're done! Thanks for your time 😄

Thanks for the help, I've added sweetening support in the new beta.
Nice mod btw :)

Your timing was spot-on, as I was about to release an update as well '^-^
Thanks once again, and thanks for making this mod!
