2 pounds yellow potatoes – peeled and cut into large chunks
3 tbsp vegetable oil
0.5 cup ajĂ amarillo paste
1.5 tsp ground cumin
1 tsp dried oregano
0.5 tsp black pepper
1 cup frozen green peas
parsley – chopped (for serving)
egg – hard-boiled and quartered (for serving)
white rice – cooked (for serving)
Instructions
Cover the tunta (chuño blanco) with cold water and soak overnight; the next day rinse several times, then simmer in fresh water until tender, 20–30 minutes, and peel off any loosened skins. Keep warm.
Prepare the onion by halving one piece for the broth and thinly slicing the other for the sauce; peel the garlic, crushing 2 cloves for the broth and finely mincing 2 cloves for the sauce.
Put the chicken, whole into a large pot and cover with cold water by about 1 inch. Add the halved onion, the crushed cloves, the bay leaves, and the kosher salt. Bring to a gentle simmer, skim, and poach until the chicken is just cooked through and tender, 35–40 minutes. Lift the chicken out and set aside; strain and reserve the broth.
Add the yellow potatoes to the hot reserved broth and simmer until they are tender when pierced, 15–20 minutes. Lift out and keep warm; reserve about 3 cups of broth for the sauce.
Heat the vegetable oil in a wide pan over medium heat. Add the reserved thinly sliced remainder and cook, stirring, until soft and lightly golden, 8–10 minutes; stir in the minced cloves and cook 30 seconds. Add the ajà amarillo paste, the ground cumin, the dried oregano, and the black pepper; fry, stirring, until fragrant and the oil tints orange, 3–4 minutes. Stir in 2 to 3 cups of the reserved broth to make a sauce and bring to a simmer.
Nestle the chicken pieces into the sauce and simmer, turning once or twice, until the sauce thickens to coat a spoon and the flavors meld, 10–15 minutes. Stir in the green peas and cook until bright and tender, 2–3 minutes. Adjust seasoning as needed.
If the tunta has cooled, briefly warm it in its cooking water and drain well.
Serve the chicken and sauce with the yellow potatoes and tunta on each plate; sprinkle with parsley and add eggs and white rice alongside.
