What is is the national food of Paraguay?

Answer 1

Mandioca - otherwise known as yucca - is the most common food found on tables all over Paraguay. And its not just in the rural areas. Its eaten at nearly every meal, 365 days a year, most Paraguayans would not eat anything without it.
Chipa is another very traditional food - shaped like bagels, they are made from mandioca flour (freshly ground), corn meal, Paraguayan cheese, eggs, pig fat/butter, anise. It is traditionally baked in a tatakua (guarani for brick oven) - that is dome shaped and heated using fire, the fire is then removed, the food is placed inside and the two openings are closed. The brick oven retains the heat (extreme heat!) and the food is cooked very quickly. Chipa is traditionally a Semana Santa (Holy Week - Easter) food. But it can also be purchased on any city/country bus by mobile vendors year round for 1.000 mil guaranies (very inexpensive snack). It is best served hot, it becomes hard when cooled.
Mandioca is similar to a potato, its a root vegetable, 100% starch. Its filling and best eaten hot. In many countries it is fryed, however, in Paraguay, it is simply peeled then boiled - no seasoning whatsoever, not even salt.
Another national food - sopa Paraguaya. Sopa in Spanish is soup, but sopa Paraguaya is a corn bread made from fresh ground corn meal, eggs, pig fat or butter, salt, Paraguayan fresh cheese, onions (optional). It is a bit expensive to make for people in the rural areas, and is often a dish made for special occasions/holidays.
Chipa guazu (big chipa) is another popular food, very similar to sopa Paraguaya. The difference is the texture, chipa guazu is "mushier" due to the corn being only slightly milled (to the texture of creamed corn, rather than corn flour used in sopa). It is quite popular during the corn harvest as it really only requires corn, eggs and cheese.
Asado, or barbecue, is a very popular meal particularly for Sundays and holidays. Beef ribs are cooked on a "parilla" or grill with only salt and lemon juice as seasoning. Pork is very popular, pigs are raised for 1-2 years in advance of a special occasion (such as a quinceanos - 15th birthday party for a girl - or a religious holiday). Generally it is prepared in a mix of lemon juice, cumin and salt and baked in the tatakua oven.
Cheap red wine is mixed with Coca-Cola for a refreshing beverage. Pilsen is the national beer, though Brahma (Brazilian brand) is even more popular, it is slightly more expensive and considered "finer." The Argentinian brand, Quilmes, is also quite popular as is Bahvarian.
