Causa Limeña
A classic Peruvian cold potato terrine flavored with aji amarillo (yellow chili) and bright lime juice, pressed into a loaf and sliced to reveal clean, golden layers. Served topped with creamy avocado, hard-boiled eggs, and fresh herbs. This elegant dish works as an appetizer, light lunch, or impressive side, with the option to fill it with shredded chicken, fish, or seafood.

Steps
Before you start
- Have all ingredients at room temperature before starting
- Line a loaf pan (9×5 inch / 23×13 cm) with plastic wrap, leaving overhang on long sides
- Hard-boil eggs at least 2 hours ahead or the night before
- If using fresh aji amarillo peppers, source them from a Latin market or order online; jarred paste is a reliable substitute
Boil the potatoes
- Place the 2 lb (900 g) unpeeled yellow potatoes in a large pot and cover with cold salted water by 2 inches (5 cm).
- Bring to a boil over high heat, then reduce to medium and simmer for 15–18 minutes, until a fork easily pierces the largest potato but the flesh isn't mushy.
- Drain in a colander and let cool for 5 minutes until you can handle them.

Ready when: Fork easily pierces potatoes but flesh is still firm, not falling apart
Tip: Don't overcook; the potatoes should hold their shape when mashed, not become gluey.
Peel and rice the potatoes
- Once cooled slightly, peel the potatoes while still warm (the skin comes off more easily).
- Pass them through a potato ricer or push through a fine-mesh strainer into a large bowl, or mash thoroughly by hand.
- Aim for a very smooth, lump-free consistency.
- Work quickly while the potatoes are still warm.

Ready when: Potatoes are smooth and free of lumps
Tip: A ricer gives the smoothest result; a masher works but may leave small lumps. Avoid a food processor, which will make the potatoes gluey.
Mix in aji, lime, and oil
- While potatoes are still warm, add the 3 tbsp (45 ml) aji amarillo paste and fold in gently using a rubber spatula.
- Then add the 80 ml (⅓ cup) fresh lime juice and fold until the mixture is pale golden and evenly colored.
- Drizzle in the ¼ cup (60 ml) olive oil and fold until fully incorporated.
- Season with ½ tsp (3 g) kosher salt and white pepper to taste.
- The mixture should be smooth, creamy, and pleasantly tangy.

Ready when: Mixture is evenly colored, smooth, and creamy with no streaks
Tip: Fold gently to avoid overworking the potatoes. Taste and adjust the lime juice and salt—it should taste lively and well-seasoned.
Press into the loaf pan
- Transfer the potato mixture to the plastic-wrap-lined 9×5-inch (23×13 cm) loaf pan.
- Using a rubber spatula or spoon, press the mixture firmly and evenly into the pan, smoothing the top.
- The mixture should be compact and fill the pan completely.
- Fold the overhanging plastic wrap over the top to seal.

Ready when: Mixture is firmly packed with a smooth, level top
Tip: Press firmly to compress the layers; this helps the causa hold its shape when sliced.
Chill and firm up
- Refrigerate the loaf pan for at least 2 hours, preferably 4 hours or overnight.
- The causa needs to chill and set so it will slice cleanly without crumbling.

Ready when: Mixture is very firm to the touch and holds its shape
Tip: Overnight chilling improves flavor and texture. You can make this up to 1 day ahead.
Unmold and slice
- Remove the pan from the fridge and let sit at room temperature for 5 minutes to loosen.
- Unfold the plastic wrap and invert the loaf onto a clean cutting board.
- Gently peel away the plastic wrap.
- Using a sharp serrated knife, slice the causa into ½-inch (1.25 cm) thick slices.
- Wipe the knife with a damp cloth between cuts for clean edges.

Ready when: Slices are uniform and hold their shape without crumbling
Tip: A serrated bread knife works better than a chef's knife for clean slices. If the causa is too cold, it may crack; room-temperature loosening helps.
Assemble and serve
- Arrange the causa slices on a platter or individual plates.
- Top each slice with a few slices of the peeled hard-boiled egg and a few slices of ripe avocado, fanning them gently on top.
- Scatter the optional crumbled cotija cheese, fresh cilantro, thin-sliced red onion, and black olives over the top.
- Serve at room temperature or chilled, with a wedge of lime on the side if desired.

Ready when: Causa is beautifully plated with all toppings arranged
Tip: Slice the avocado just before serving to prevent browning. If making ahead, add avocado and eggs only when ready to serve.
Good to know
Tips
- For a richer, more substantial dish, layer the potato mixture with shredded poached chicken, crab, or white fish in the middle. Divide the potato mixture in half, press half into the pan, add a layer of filling (about ¾ cup / 180 ml), then top with the remaining potato mixture.
- Aji amarillo paste can be found in Latin markets, specialty grocery stores, or online. If you can't find it, fresh aji amarillo peppers can be simmered with a little vegetable broth, blended, and strained. Some cooks use a mix of yellow bell pepper and a touch of habanero or other yellow chili for a closer homemade version.
- Serve causa with traditional Peruvian sides like ceviche, arroz amarillo (yellow rice), or fresh ceviche sauce (leche de tigre) on the side for dipping.
- For a vegetarian or vegan version, omit the eggs and cheese, and garnish instead with extra cilantro, sliced red onion, and olives. The causa itself is vegetarian and naturally vegan if made with olive oil.
Make ahead
The potato mixture can be made and pressed into the pan up to 1 day ahead; refrigerate covered. Slice and top with avocado and eggs just before serving. If using hard-boiled eggs, prepare them 1–2 days ahead and store in the fridge until needed.
Storage & reheating
Room temperature: up to 2 hours (but best served shortly after assembly). Refrigerator: store the unsliced causa (covered) for up to 2 days; sliced causa lasts 1 day. Do not freeze—the potato texture will degrade. To reheat, bring slices to room temperature (about 20 minutes) before serving.
Substitutions
- aji amarillo paste (or 3–4 fresh aji amarillo peppers, seeded and blended) → Aji amarillo powder mixed with a little water, or substitute with 2 tbsp (30 ml) of jarred yellow chili paste (easier to find and nearly identical in flavor). The paste is essential to the dish's signature color and slightly spicy, citrusy flavor. Avoid substituting with other chili colors, as it changes the character of the dish.
- yellow potatoes (such as Yukon Gold or Peruvian amarilla) → Yukon Gold or other waxy yellow potatoes (not russets, which are too starchy and will become gluey). The waxy texture and pale color of yellow potatoes are key to the dish. Russets won't give the correct consistency.
- cotija cheese (or queso fresco) → Feta cheese, queso fresco, or even a crumbling of aged Manchego if cotija is unavailable. Cotija's saltiness and crumbly texture are traditional, but similar cheeses work. Avoid soft cheeses like mozzarella.
- ripe avocado → If avocados are not ripe, use thin slices of lime-dressed hearts of palm or cucumber, or thin slices of cooked chicken breast mixed with a light mayonnaise. Avocado's creaminess is traditional, but it can be hard to source ripe ones. Hearts of palm offer a similar texture and are shelf-stable.
