Peanuts are a type of legume, though they are used in similar ways to nuts for culinary purposes.
Peanuts, covered in a fungus in an attempt to enhance their flavour to the point where a ghost could taste them, where among the snacks served at Nicholas de Mimsy-Porpington's five-hundredth Deathday Party. Peeves offered a bowl of these peanuts to Hermione Granger, who refused the offer, and later threw them through Myrtle Warren while mocking her for being pimply. Normal peanuts were also among the snacks served at an impromptu party held in the Gryffindor common room to celebrate Harry Potter being named a Hogwarts champion in the Triwizard Tournament.
Ronald Weasley, upon remembering a time that his brother Fred tricked him into trying an Acid Pop, contemplated if Fred could in turn be tricked into eating Cockroach Clusters if he thought they were peanuts. Honeydukes sells bags of roasted peanuts.
