Chipa is a type of small, baked, cheese-flavored rolls, popular snack
and breakfast food in Paraguay. The recipe has existed since the 18th
century and its origins lie with the Guaraní people of Asunción. It is
inexpensive and often sold from streetside stands and on buses by
vendors carrying a large basket with the warm chipa wrapped in a cloth.
The original name is from Guarani chipa. A small chipa may be called a
chipita. In Santa Cruz de la Sierra, Bolivia, the term cuñapé (Guarani)
is often used. In some parts of Argentina, it is called chipá (with an
accent mark), or chipacito when it is small.
