Notes
The popular origin story, women from Huancayo feeding railway workers during construction of the Ferrocarril Central in the 19th century, including a specific named figure in some tellings, is genuinely contested rather than settled: Peruvian sources themselves describe the dish's origin as controversial, and no single account has clearly displaced the others.
What a modern chef changes
A fully smooth sauce, an even potato texture
Method
- Blend the sauce in the high-power blender at a lower, longer speed than a home blender allows, then pass it through the chinois for insurance.
- Confit the potato slices gently sous vide before chilling, for an even, buttery texture edge to edge rather than the slightly overcooked rim a boiled potato can carry.
- Toast the ají amarillo briefly before blending, in a dry pan or under the Big Green Egg's direct heat, for a rounder, less raw chilli note through the finished sauce.
