Dairy products can only be made on Members' worlds with a Dairy churn. A Dairy churn is found on the farm south of Falador, the cooking guild just south of the Grand Exchange and at several other locations. If a player is contemplating a major churning project, it is worth noting that churning is very slow work. Also, as the bucket and dairy item are both retained, all things made at the churn can only be made in sets of 14, along with 14 empty buckets. The buckets do get automatically dropped if the player's inventory is full, so 28 can be churned in one go, if the player does not mind the loss of the buckets.
