After this you begin the quest by interacting with a sign fragment in the rubble below the broken bridge on the Timeless Isle. This begins Noodle Secrets Long Forgotten which send you to search Old Pi'ju for the owner of the sign fragment. After this you will be sent to Temple of the Jade Serpent to complete The Lost Secret of the Secret Ingredient. This can be completed in normal or heroic mode, but make sure not to leave the instance after the Sha of Doubt is defeated because the quest is finished inside the instance. Then you will have to defeat a mini-boss for Bad Feeling, Worse Result while still inside the dungeon.
The next part of the chain will have you completing several quests in the Valley of the Four Winds. Catch and Carry is a little mini-game to catch falling sacks of grain at the Imperial Granary. The next quest, Is That a Real Measurement? will send you into the Stormstout Brewery to collect items from the alementals at the end of the instance. It can be completed on normal or heroic. You will also need to create your first Noodle Cart Kit. After this, you will learn the recipe to create 250 stat carts. The full list of materials needed will be at the bottom of this post.
These Aren't Your Fatty Goatsteaks sends you back to the Timeless Isle to collect 50 Fatty Turtle Steaks from any turtles on the island (don't worry, the elite's drop multiple steaks). In addition, you will have to create your first Deluxe Noodle Cart Kit. When you're all done, make your way back to Halfhill.
The Secret Ingredient Is...
will have you complete the new cooking scenario of running the noodle stand at Halfhill, which involves you seating and feeding customers. Depending on the customer, they will prefer certain types of noodle soups and hungry ones want to eat two of them. When a new customer shows up, you click on them, and then click on the table you want them to sit. They will wait a short time for the food, and if you don't feed them in time they will leave. You use the special action buttons to cook the various soups, then click on a soup and then one of the seated customers to feed them. This information is all available in the tooltips on the special action buttons. Don't be alarmed if you fall behind as you learn who likes what. You will complete it eventually. Your reward is the recipe for the Pandaren Treasure Noodle Cart Kit (300 stat food). You can also do this scenario as a daily quest to earn Ironpaw Tokens
