Punjabi Chandu Halwai Karachiwala is a well-known halwai shop in Mumbai. It was originally established in Karachi in 1896.
Its owners moved to Mumbai after the partition of India. Karachi Halwa, also known as Bombay Halwa was popularized by halwais moving from Karachi.
While many preparations remain traditional, they occasionally develop new sweets.
Feeding of refugees
Sri Prakasa, the first High Commissioner to Pakistan, recalled an incident during the days of partition, when he faced the problem of feeding the refugees in Karachi in 1947. He was able to get the food supplies from Chandu Halwai. Chandu Halwai refused to take the payment for the food.
