The technique of softening the bread in the steam packer is quite clever; steaming ordinary homemade buns in this way gives a nice soft texture like that of the store. I completely agree with the warning given about the health risks and cost of street food. The sauces or oils used outside are not always of high quality, so simple homemade recipes are much safer for children. In my opinion, the real attraction of street food lies in its quick and spicy taste, but when it is made at home, you can enjoy that taste without taking any health risks. And the memory you shared of Trinidadian chicken roti is wonderful; the taste of food when traveling or living in a different country really sticks in your mind. Best of luck to you in this contest. 😊
