Top-quality milk

A Top-quality milk is a quest item that is obtained during the Cook's Assistant quest. The bucket of top-quality milk is obtained by milking the Prized dairy cow (which is held to the ground by use of a red rope) east of Gillie Groats in the Lumbridge cow field. The cow field is located across River Lum near the Lumbridge Furnace.

When a player tries to milk a normal Dairy cow with Top-quality milk in their inventory they will receive a message to give the Cook the Top-quality milk before continuing.

Trivia

 * Before the release of Top-quality milk on the 15th of December 2009, players needed a normal bucket of milk to complete the quest Cook's Assistant.
 * It appears that it is slightly overflowing.
