Garlic

Garlic is used for the Fishing Contest and Vampire Slayer quests. Despite being a food, it cannot be used in the Cooking skill, nor can it be eaten.

Where to find garlic:

On a table in a house in Seer's Village.

On a table in a house near the marketplace in Ardougne.

In a cupboard in Morgan's house, second floor, in Draynor Village.

Buy or thieve from Greengrocer vegetable stall in Etceteria and Miscellania.
