Petha is a traditional Indian sweet made primarily from ash gourd, also known as winter melon. The process involves peeling the gourd, boiling it, and then soaking it in sugar syrup, which gives it a translucent appearance and a sweet flavor. Petha is often flavored with cardamom or rose water, enhancing its taste and aroma. Originating from the city of Agra, petha is popular across India and is often enjoyed during festivals and special occasions. It is available in various forms, including plain, flavored, and even colored varieties, making it a versatile treat for sweet lovers.
