The story
Chuño is one of the oldest continuously-produced foods in the Americas: freeze-dried potato, made by exposing potatoes to the freezing cold of Andean nights and the hot high-altitude sun of the days, alternately freezing them solid and then trampling them underfoot to press out the water and skin. The finished chuño is small, dark, wrinkled, rock-hard, and keeps for years in a dry storeroom — the Andean peoples of Peru and Bolivia have been making it for at least 2,000 years, and it was the primary food supply of the Inca Empire's army and treasury. Modern chuño is still made in the Peruvian and Bolivian altiplano; it's sold at markets in Cusco, Puno and La Paz, and used as an ingredient in soups (chairo, chuño soup), stews and the specific dish of chuño phuti (Bolivian scrambled eggs with reconstituted chuño).
Method
Rinse the chuño under cold water. Cover with plenty of cold water in a bowl and soak overnight (or at least 8 hours). The chuño will soften and swell.
Drain the soaked chuño. Cover with fresh cold water in a pot. Bring to a boil, then simmer 25 to 30 minutes until fork-tender. Drain and rinse briefly under cold water. Chop the softened chuño into small dice.
Warm oil in a wide heavy pan. Cook onion 6 minutes until soft. Add garlic 60 seconds.
Add ají amarillo paste, cumin, oregano, salt and pepper. Cook 3 minutes, stirring, until the paste has darkened and the oil separates.
Add the chopped rehydrated chuño. Toss to coat in the aromatic base. Pour in the stock. Simmer 5 minutes so the chuño absorbs the flavours.
Whisk the eggs with 1 tsp salt in a bowl. Pour into the chuño mixture. Stir slowly with a wooden spoon or spatula, folding gently, until the eggs are just set into soft, silky scrambled curds — about 3 to 4 minutes.
Off the heat, fold in the crumbled cheese and crema. The cheese should soften into the eggs. Taste and adjust salt.
Tip onto plates alongside a scoop of steamed rice or quinoa. Scatter with chopped coriander. Squeeze lime juice generously over the top. Top with sliced red onion. Serve immediately with ají amarillo salsa on the side.
Tips
- Overnight soak is not optional. Chuño is rock-hard from years of storage. It needs 8 hours minimum to rehydrate. Skipping the soak gives you inedibly hard chuño even after boiling.
- Boil until fork-tender. Undercooked chuño is chewy in a bad way. Well-cooked is soft, slightly earthy, absorbs flavours.
- Ají amarillo is the flavour marker. Without it the dish tastes plain and starchy. Fresh or paste — either works.
- Fold, don't scramble hard. The eggs should stay silky and soft — this is Peruvian scrambled eggs, not diner scrambled eggs. Fold gently with a wooden spoon.
- Lime at the end. The bright acidity is essential — it cuts the earthiness of the chuño and the richness of the cheese and eggs.
