I've always wanted to say that. Normally, I'd debut a new drink at a banquet, but we can't have one in the middle of the jungle.
Instead, just take samples to a few trusted friends and return with their comments. Let's see, we'll definitely want Hemet Nesingwary's opinion, and Hadrius Harlowe's, too. They're here in camp. You'll want to head over to Lakeside Landing, near the center of the Basin and offer Tamara Wobblesprocket a taste.
Don't keep me waiting, <name>. What are the results?
Completion
Two out of three drinkers agree, eh? Not bad for a first try. Not bad at all. I suppose I'll have to whip up something else for Tamara by the way of apology.
Now... what should we call this creation? How about Kungaloosh? I like the sound of that!
Notes
While Hemet and Hadrius are at the camp, you'll need to get to Lakeside Landing at River's Heart to speak to Tamara.
You must complete the following quests before the chain is available:
Patch 3.0.8 (2009-01-20): A recipe has been added for Kungaloosh. You can learn this recipe from an NPC in the Dalaransewers once you have completed the quest 'The Taste Test' in Sholazar Basin.
