History of causa

Causa literally means “cause” in Spanish. There’s a bit of a debate as to where it got its name. Some believe that the name derives from the Quechua word “kawsay,” which means “food.” However, most Peruvians will tell you that José de San Martín, known as the Protector of Peru, coined the term. Legend has it that during the fight for Peruvian independence from Spain, he called for Peruvians to support the cause for independence by providing food for their soldiers. At this time one of the most common dishes happened to be this very same layered potato dish. From then on, the dish was called causa. (“Rellena” means “stuffed” in Spanish).

Ingredients

Potato layer

  • 2 lb yellow potatoes, peeled
  • 4 Tbsp olive oil
  • 4 Tbsp lime juice
  • 1-2 Tbsp ají amarillo paste (yellow Peruvian chili pepper)
  • Salt and pepper, to taste

Preparation
  1. Peel and boil your potatoes until soft.
    Tip: Make sure to use yellow potatoes. They are waxier than white potatoes and hold their form when boiled. 
  2. Mash the potatoes. Then mix in the olive oil, lime juice, ají amarillo, and salt and pepper to form a smooth mixture. Afterward, let cool.
    Tip: For extra smoothness, sieve the mixture to remove any fibrous potato. 
  3. In a separate bowl, combine the chicken, tuna, or vegetarian/vegan substitutes with lime juice, mayonnaise, onion, and tomato. Salt and pepper to taste. 
  4. When the potato mixture has cooled to room temperature, evenly spread half of it in the base of a Pyrex dish. Tightly pack the mixture in order to prevent breakages. This will firm up once refrigerated.
    Tip: Line a Pyrex dish with cling wrap, leaving extra to overhang. The extra will be used to round off the top layer. This method makes serving easy and mess-free.
  5. For the next layer, neatly arrange sliced avocado. Then, on top of the avocado, add your chicken, tuna, or veggie-friendly mix. Be careful not to squash the layers below.
  6. Add the remainder of your potato mixture to form the top layer. If using cling wrap, pull over the top layer to create a brick shape.
  7. Refrigerate for 3+ hours. When it’s time to serve, turn the causa out onto a plate and unwrap.
