YO. I have been searching for a way to grind to level 47 fast! I found it (I think) - January this year there was a reward for a goal, the appliance name is "WINTER FROST FOUNTAIN" - The drink is called White Hot Chocolate. The amazing thing about this recipe is that it only cost 170 GOLD. and you get 66 XP for just PREPARING. If you only have the Winter Frost Fountain, you'll have to prep, pick up, prep, pickup - and so on. If someone has a better recipe for the price let me know!! or let me know if this helps you!!!
P.S this isn't obtainable unless you completed some of the goal from January this year. Test it .
It requires x5 frosted glass + x5 winter branches per machine.
If you had 10 of these you could whip up some serious XP per hour. or if you completed all the goals so you didn't have to pick it up and set it down (This really puts a strain on your xp/hr)
