Causa Limeña (Peruvian Chilled Potato Terrine)

About This Recipe

Causa limeña is one of Peru's most elegant and distinctive dishes — a cold layered terrine made from yellow potato mashed with aji amarillo paste, lime juice, oil and salt, layered with creamy fillings of avocado, tuna or chicken salad, and presented in decorative slices or individual portions. The dish is deceptively simple in concept but extraordinarily satisfying: the potato layer has a firm but yielding texture and an unmistakable flavor from the aji amarillo, Peru's national chile, which gives it a vivid golden-orange color and a fruity, moderately hot warmth that no other ingredient in the world can replicate. The word 'causa' likely derives from the Quechua 'kausay', meaning sustenance or life — a fitting name for a dish that has nourished Peruvians for centuries. Potatoes are native to Peru, cultivated in the Andes for at least 7,000 years, and the variety used for causa — the papa amarilla, a waxy, dense, intensely flavored yellow potato — is unique to Peru. Outside Peru, Yukon Gold potatoes are the closest available substitute, offering the right texture and a similar yellow-gold interior, though the flavor is milder. Causa appears in Lima's restaurants as both a street snack (small individual portions) and as a formal first course (sliced terrine with decorative garnishes). In home cooking it is typically prepared for Sunday lunches, family gatherings and birthday parties. The assembly allows for enormous creativity: vegetarian causas with avocado and vegetables, seafood causas with shrimp cocktail filling, and even causa with crab and quail eggs are found in Lima's contemporary Peruvian restaurants.

Ingredients

Serves 6

• 1 kgYukon Gold potatoes(or Peruvian papa amarilla if available)
• 3 tbspaji amarillo paste(jarred; adjust for heat preference)
• 3 tbspneutral oil(vegetable or light olive oil)
• 3 tbspfresh lime juice
• 1.5 tspsalt
• 2ripe avocados(sliced thin)
• 300 gcooked chicken breast(shredded; or 2 cans (160g each) good-quality tuna)
• 4 tbspmayonnaise
• 1 stalkcelery(finely diced)
• 2 tbspred onion(finely diced)
• 1 tbspfresh lime juice(for the chicken/tuna salad)
• 0.5 tspsalt(for the filling)
• 2 tbspmayonnaise(for spreading between layers)
• 4black olives(sliced, for garnish)
• 1 tbspfresh parsley or cilantro(for garnish)

Instructions

1. 1

   Cook and rice the potatoes

   Boil potatoes in salted water until completely tender when pierced with a knife, about 20–25 minutes. Drain, peel while still warm (the skins slip off easily) and rice or mash immediately while hot. Do not use a food processor — it activates the starch and produces gluey potato.

   Ricing the potatoes while they are warm and then letting them steam-dry for 5 minutes before adding the oil produces the smoothest, lightest causa masa.

2. 2

   Season the potato mixture

   To the riced warm potato, add aji amarillo paste, oil, lime juice and salt. Mix thoroughly until completely combined and the potato is a uniform golden-yellow color. Taste and adjust — it should taste distinctly of aji amarillo, lime and salt. Let cool to room temperature.

3. 3

   Make the filling

   Combine shredded chicken (or drained tuna) with mayonnaise, finely diced celery, red onion, lime juice and salt. Mix well and taste for seasoning.

4. 4

   Assemble the causa

   Line a loaf pan or deep rectangular dish with plastic wrap, leaving overhang on all sides. Press half the potato mixture into the bottom, smoothing with wet hands or a spatula into an even 2 cm layer. Spread 1 tbsp mayonnaise over the potato layer. Arrange sliced avocado in a single layer over the mayonnaise. Spread the chicken or tuna filling evenly over the avocado. Press the remaining potato mixture over the filling, smoothing to an even layer. Cover with the overhanging plastic wrap.

5. 5

   Chill and unmold

   Refrigerate at least 2 hours until firm. To serve, lift out using the plastic wrap overhang and place on a serving platter. Peel back the plastic wrap. Slice into portions with a sharp knife dipped in hot water. Garnish each slice with sliced olives, a dot of mayonnaise and parsley or cilantro.

Variations

• •

  Causa de camarones: replace the chicken or tuna filling with chilled poached shrimp tossed in spicy mayonnaise with a little aji amarillo paste — a seafood version popular in Lima's ceviicherías.

• •

  Causa vegetariana: fill with roasted vegetable ratatouille, sliced avocado and crumbled fresh cheese — a popular contemporary version found throughout Lima.

Storage

Assembled causa keeps refrigerated, wrapped in plastic, for up to 2 days. The potato hardens slightly when very cold — slice and plate straight from the fridge. Do not freeze — the potato texture becomes grainy and the avocado oxidizes and discolors.
