Causa Limeña (Peruvian Andean Tradition)
A vibrant Peruvian classic where chilled, resistant-starch potatoes meet wild-caught salmon and creamy avocado. The dressing relies on fresh ají amarillo and lime for brightness without refined sugar or seed oils.
A little context
Traditional Causa often uses vegetable oil and a pinch of sugar to balance the heat of the ají. We substitute extra virgin olive oil and rely on fresh lime and high-quality paste for acidity, keeping the dish anti-inflammatory without losing the authentic tart-spicy profile.
The longevity story
Cooling the potatoes creates resistant starch, which feeds beneficial gut bacteria and lowers glycemic impact. Wild-caught salmon provides astaxanthin and omega-3s for cellular health, while extra virgin olive oil delivers potent polyphenols like hydroxytyrosol. The absence of refined sugar and seed oils minimizes inflammatory markers while maximizing nutrient density.
Method
- 01
Boil and cool potatoes
Boil potatoes in salted water until tender but not falling apart. Drain, cool completely in the fridge for at least 2 hours to maximize resistant starch.
- 02
Mash the base
Press cooled potatoes through a ricer. Mix with 2 tbsp lime juice, 1 tbsp ají amarillo paste, 30 ml olive oil, and salt. Taste for balance.
- 03
Prepare the salmon
Pat salmon dry, salt lightly. Sear skin-side down in a hot dry skillet until crispy, then flip and cook 2 minutes more. Flake into chunks.
- 04
Make the dressing
Whisk remaining 60 ml olive oil with 2 tbsp lime juice and a pinch of salt until emulsified.
- 05
Assemble layers
In a bowl or ring mold, layer half the potato mixture, then salmon, then sliced avocado and red onion. Top with remaining potato mixture.
- 06
Finish and serve
Drizzle with dressing. Garnish with sliced hard-boiled eggs and fresh cilantro. Serve immediately or keep chilled.
Pro tips
- ✦Cooling the potatoes is non-negotiable for gut health; it creates resistant starch that survives digestion.
- ✦Source wild-caught salmon to ensure a superior omega-3 profile compared to farmed varieties.
- ✦If ají amarillo paste is unavailable, blend fresh yellow peppers with lime and salt for a fresh version.
- ✦Use a ring mold for plating to keep the layers distinct and visually striking.
- ✦Choose avocados that yield slightly to pressure but are not mushy for clean slicing.

Substitutions
- wild-caught sockeye salmon → wild-caught tuna or trout (maintains high omega-3 content and clean protein profile)
- yellow potatoes → purple potatoes (adds anthocyanins but requires longer cooling time)
- red onion → pickled pearl onions (ensure pickling brine has no added sugar)
Storage
fridge 3 days in a glass container; freezes well portioned up to 2 months
What to serve with it
- green tea with lemon

- kombucha (low sugar)
FAQ
Can I use farmed salmon?+
You can but the omega-3 profile is weaker and the feed is typically corn-based. Wild is the point.
Is this recipe low-carb?+
It contains starch from potatoes, but cooling them lowers the glycemic load significantly. Portion control applies.
Can I make this vegan?+
Yes, omit the salmon and eggs. Add extra avocado or chickpeas for protein and texture.
