Eating India Cuisine
When eating with your hands use the right hand. Using the left hand is prohibited and considered unclean in India. Just like in America, people are expected to come to America and now proper protocol when eating our dishes. So, make sure you extend the same courtesy when you travel outside the country. (Respect their way of life). In India there is the dish called Raita. You are allowed to sip from your spoon eating this dish. Other dishes that are heavy with rise such as biryani it is best to eat with your utensils. If you choose to use your fingers simply put the rice in a pile before sticking it into your mouth. This will help the rice to stick together making it easier to eat.
Eating Ethiopian Cuisine
In Ethiopia it is considered bad luck to eat with your left hand (just like in India). If you are left handed this is good time to practice using your right hand. This is considered proper etiquette in Ethiopia.
