Vishu is a significant festival in Kerala, marking the start of the Malayalam New Year on April 15. The celebrations include the Vishukkani ritual and a grand vegetarian feast known as Vishu Sadhya. This elaborate meal, traditionally served on banana leaves, features a mix of sweet, salty, sour, and bitter dishes, symbolizing abundance and the varied experiences of life. Signature dishes include mambazha pulissery, a mango curry, vishu kanji, a nourishing porridge, and veppampoorasam, a bitter dish made with neem leaves. The term 'Sadhya' comes from Sanskrit, meaning feast, and has evolved from temple rituals and agrarian celebrations. This cultural feast reflects Malayali identity and is a cherished tradition during Vishu and other celebrations.
