Food on the Road
For what Argentina lacks in fresh produce when compared to its neighbors in Chile, it makes up for in meat products, especially beef. Its surprising how much the average Argentine knows in regards to the anatomy of a cow.
Stock up on camping food like peanut butter and cous-cous when you can find them.
Disposable butane/propane gas canisters for camping stoves are easy to come across in bigger towns.
Bring your flavorings and spices with you from home, as there are not many options available in markets in Argentina. If you are in Chile and are traveling to Argentina, be sure to stock on up spices.
Argentina is a great country to visit for those with a sweet tooth. There are many bakeries that sell dulce de leche filled pastries.
