Hello. I am looking for high-quality, convenient and delicious frozen momos, I would like to know what factors I should consider when choosing a brand. For example, what ingredients are used in the filling, is the outer layer made of whole wheat flour or refined flour, what kind of preservatives are used, if any, and are the momos non-GMO and organic. Can anyone provide me with this information and any other relevant details to help me make an informed decision when buying frozen momos?
