Items required: Bread, an orange, a knife, dye (other than red, yellow, orange, or pink), spice, fishing bait, a bucket of water, and charcoal.
First, inspect the frozen goblin generals in the Lumbridge Castle dining room to start the quest.
Go to the Goblin Village, enter the building just south of the generals and climb down the ladder. You will see Mudknuckles, a goblin cook. He will tell you to get him some charcoal to finish a cooking recipe that he overheard two dwarves talking about. Give him the charcoal. He will add it to his cauldron, which will explode in a hilarious cutscene. Miraculously, you both survive.
The chef claims it worked.
Mudknuckles will then tell you that he has trouble with the food, as both the generals are bickering over it. To make food for the generals, he needs oranges that aren't orange, maggots that aren't bland, and bread that isn't crunchy. You can make the ingredients listed below:
Give all three to Mudknuckles to get the Slop of compromise. Give it to the goblin generals in Lumbridge to complete this part of the quest.
