VIETNAMESE SNACKS

Vietnamese peasants used to have a lot of free time after the busy crop time passed, and preparing some nosh to eat is a certain result of the circumstance. Sweet potato is a prime example of the case. It is considered the most popular nosh in the countryside. Ever experience Vietnam home-staying? You must realize boiled sweet potato, cassava and peanuts are the most typically Vietnamese snacks - of course without salt or sugar added.

And if you dare venture beyond the standard ones, there are surely bizarre things to try. The best place to taste purely Vietnamese snacks is to have them right in a family or on the sidewalks along every street. Tasting a fertilized egg at 4 pm on a breezy afternoon may scare you, yet it is one of the most popular snacks out here and is considered extremely nutritious.

Besides varieties of wonderful noodle, made-of-rice cakes, bean sweet soups you may be too shy to eat a bowl of pig raw blood soups. Does it originate from Totem belief? Not many Vietnamese questions that when eating the dish. All they want to do is to choose the right restaurant and wait to be served the raw blood soups with Vietnamese spirit.

1. When do Vietnamese farmers used to have lots of free time?

2. What is considered the most popular nosh in the countryside?

3. What are the most typically Vietnamese snacks?

4. Are blood soups can be served in restaurants?
