The mashed potato mixture is then layered with a variety of fillings, such as tuna, chicken, avocado, seafood, or vegetables. Causa can be served cold or at room temperature, making it perfect for parties, picnics, or a light meal.

Step-by-Step Instructions

Part 1: Preparing the Potatoes

1. **Boil the Potatoes:** Wash the potatoes thoroughly. Place them in a large pot and cover them with cold water. Bring the water to a boil over high heat, then reduce the heat to medium and simmer until the potatoes are tender and easily pierced with a fork, about 20-25 minutes. The cooking time will vary depending on the size of your potatoes. It is crucial that potatoes are tender to create a smooth mash.

2. **Peel the Potatoes:** Once the potatoes are cooked, drain them immediately. While they are still hot (but cool enough to handle), peel off the skins. Peeling hot potatoes can be tricky; you can use a fork to hold them steady while peeling with a knife or use a potato peeler.

3. **Mash the Potatoes:** In a large bowl, mash the peeled potatoes while they are still warm. You can use a potato masher or a potato ricer for a smoother texture. A ricer will create a significantly smoother mash, which is preferred for causa. Avoid over-mashing, as this can make the potatoes gluey.

4. **Season the Potatoes:** Add the vegetable oil (or olive oil), lime juice, and aji amarillo paste to the mashed potatoes. Mix well until all ingredients are thoroughly combined and the mixture is smooth and creamy. Taste and adjust the seasoning with salt and pepper as needed. The amount of aji amarillo paste will determine the heat level, so start with less and add more to your preference. The lime juice adds a crucial tanginess that balances the richness of the potatoes and aji amarillo.

5. **Cool the Potato Mixture:** Cover the bowl with plastic wrap, pressing the plastic directly onto the surface of the potato mixture to prevent a skin from forming. Refrigerate for at least 30 minutes to allow the flavors to meld and the mixture to firm up. Chilling the potato mixture is essential for easy handling when assembling the causa.

Part 2: Preparing the Filling

Choose your desired filling from the options below, or get creative and make your own!

**Option 1: Tuna Filling**

1. **Drain the Tuna:** Open the cans of tuna and drain them thoroughly, removing any excess water or oil.
2. **Combine Ingredients:** In a medium bowl, combine the drained tuna, mayonnaise, finely chopped red onion, lime juice, and chopped cilantro. Mix well until all ingredients are evenly distributed.
3. **Season to Taste:** Taste and season with salt and pepper as needed.

**Option 2: Chicken Filling**

1. **Shred the Chicken:** Ensure your cooked chicken is shredded into small, manageable pieces. You can use two forks to shred the chicken or use your hands.
2. **Combine Ingredients:** In a medium bowl, combine the shredded chicken, mayonnaise, finely chopped celery, and lime juice. Mix well.
3. **Season to Taste:** Taste and season with salt and pepper as needed.

**Option 3: Avocado Filling**

1. **Mash the Avocado:** In a medium bowl, mash the ripe avocados with a fork until smooth. Ensure there are no large lumps.
2. **Combine Ingredients:** Add the lime juice, finely chopped red onion, and chopped cilantro to the mashed avocado. Mix well.
3. **Season to Taste:** Taste and season with salt and pepper as needed. The lime juice prevents the avocado from browning.

Part 3: Assembling the Causa

1. **Prepare Your Work Surface:** Lay out a large piece of plastic wrap on your work surface. This will make it easier to lift and transfer the causa.

2. **First Potato Layer:** Divide the chilled potato mixture in half. Take one half and spread it evenly over the plastic wrap, forming a rectangular or square shape, about 1/2 inch thick. Use your hands or a spatula to create a smooth and even surface. Ensure the potato layer is uniform in thickness for a consistent texture in the final product.

3. **Add the Filling:** Spread your chosen filling evenly over the potato layer, leaving a small border around the edges. Don’t overfill the causa, as this will make it difficult to roll or layer neatly.

4. **Second Potato Layer:** Take the remaining half of the potato mixture and carefully spread it over the filling, creating another even layer. Again, ensure the potato layer is uniform in thickness. This can be a little tricky, so work gently and patiently.

5. **Shape the Causa (Option 1: Roll):** Using the plastic wrap, gently lift one edge of the potato layers and begin to roll the causa into a log shape, similar to a sushi roll. Tuck the plastic wrap in as you roll to create a tight and even roll. Once rolled, wrap the causa tightly in the plastic wrap and refrigerate for at least 1 hour to allow it to firm up. This helps the causa hold its shape when sliced.

6. **Shape the Causa (Option 2: Layer in Dish):** Alternatively, you can layer the causa in a serving dish or individual ramekins. Place half the potato mixture at the bottom, followed by the filling, and then top with the remaining potato mixture. Gently press down on each layer to ensure they are compact. Cover the dish with plastic wrap and refrigerate for at least 1 hour.

7. **Slice and Serve (Roll):** If you rolled the causa, remove it from the refrigerator and carefully unwrap it. Use a sharp knife to slice the causa into 1-inch thick rounds. For clean slices, use a wet knife. Wipe the blade clean between slices.

8. **Serve and Garnish:** Arrange the causa slices or layered causa on a serving platter. Garnish with hard-boiled egg slices, olives, avocado slices, red bell pepper strips, and cilantro sprigs, or any other desired garnishes. Garnishes add visual appeal and complement the flavors of the causa.

Tips for Success

* **Use the Right Potatoes:** Peruvian yellow potatoes (papa amarilla) are the traditional choice for causa. They have a naturally creamy and slightly sweet flavor. If you can’t find them, Yukon Gold potatoes are a good substitute.
* **Don’t Overcook the Potatoes:** Overcooked potatoes can become waterlogged and gluey. Cook them until they are just tender enough to be pierced with a fork.
* **Mash the Potatoes While Hot:** Mashing the potatoes while they are still hot will help them become smooth and creamy.
* **Adjust the Aji Amarillo Paste:** Aji amarillo paste can vary in spiciness. Start with a small amount and add more to your liking.
* **Chill the Potato Mixture:** Chilling the potato mixture before assembling the causa will make it easier to handle and prevent it from sticking to your hands.
* **Refrigerate After Assembling:** Refrigerating the assembled causa for at least an hour will allow the flavors to meld and the layers to firm up.
* **Get Creative with Fillings:** Don’t be afraid to experiment with different fillings. Other popular options include shrimp, crab, chicken salad, and vegetable combinations.
* **Presentation Matters:** Causa is a beautiful dish, so take the time to garnish it attractively. Use colorful ingredients like hard-boiled eggs, olives, avocado, and bell peppers.

Variations

* **Causa Rellena de Atún (Tuna Causa):** This is the most classic version, filled with tuna salad.
* **Causa Rellena de Pollo (Chicken Causa):** Filled with shredded chicken salad.
* **Causa Rellena de Camarones (Shrimp Causa):** Filled with cooked shrimp and a creamy sauce.
* **Vegetarian Causa:** Filled with layers of avocado, asparagus, carrots, and other vegetables.
* **Causa Limeña:** A more elaborate version with layers of potatoes, avocado, chicken or tuna, and a creamy sauce.

Serving Suggestions

Causa is typically served as an appetizer or a light lunch or dinner. It can be served cold or at room temperature. It pairs well with other Peruvian dishes, such as ceviche or anticuchos. It’s also a great addition to a buffet or potluck.

Storage Instructions

Leftover causa can be stored in an airtight container in the refrigerator for up to 2-3 days. Keep in mind that the texture may change slightly upon refrigeration.
