Refreshing Lemon Barely Water

In 1918 my Great Grand father Shri Abdulhusain Alibhai Kalvert established a small unit namely M/s. A.Kalvert & Company, at Duncan Road, Bombay 10 with workforce of 5-6 workers. He was the person who made the products and delivered it by carrying it on his back. He used to make ready to eat foods like Biryani, Mutton Kurma etc. for the purpose of military supply when our Jawans were fighting against enemy at Eastern Borders when we were under the British Rule.
