Many hypotheses exist about the history of this meal, but the most accepted one places the roots in the modern era of Peru, specifically during the Pacific War that confronted Peru and Chile .

It was a conflict that lasted for more than four years and marked the history of South America because it defined the frontiers that separate these two countries and Bolivia.   

At the time, the Peruvian army was suffering severe financial shortages, and it was a challenge to keep the troops fed. The situation was so critical that each soldier received only a piece of cheese per day.

As they moved through the towns, they received the support of the residents, especially the ladies, whom boiled potatoes and offered them to the soldiers.

When giving them the potatoes, the ladies used to say “for the cause” as a sign of support for the common purpose to defeat the Chileans.

The soldiers kept the boiled potato inside their pants’ pocket, and when they had a chance to eat during the battle, what they found was mashed potatoes and opted to wrap their army given piece of cheese with the mash.

Since then, the combination began to become famous, and Peruvian cooks started to more flavors to it. Today it is one of the recipes that most represents Peruvian cuisine.

The base of the dish historically is the potato, specifically the yellow potato. You boil the potatoes and mash them and add some other ingredients (you can find the whole recipe at the end of this article).

The filling also varies today. You can use tuna, chicken, crab, and even beef. Avocado, tomatoes, and onions are also part of the dish. It is so versatile that Peruvian-Japanese restaurants now make maki rolls substituting the rice for the cause dough.
