As the “zero-waste” movement catches on, people are looking to the tiffin carrier as a convenient way to bring their own lunches, to cut back on the unnecessary waste associated with take out food.
Traditionally, the bottom layer of the carrier contains the carbohydrate of the meal, which is often bread, naan or rice. The next layer would contain a salad or pickle, and the third the protein-rich bulk of the meal, such as curry, to be eaten with the rice or bread.
The main advantage of the Tiffin style carriers are keeping the foods separate, in a structured container, to prevent your lunch from getting soggy or squashed before you can eat it. They come in 2, 3 or 4 layer styles, typically made with stainless steel.
