Gourmet May 2009, Comfort food, Peruvian style. The chile sauce’s brilliant yellow hue comes from a pinch of turmeric, as well as bottled ají amarillo paste, which also lends a fruity heat. It is thickened with bread and walnuts (a tasty trick for stretching foods to feed many mouths) and blended to a satiny smoothness. Although Peruvian cooks usually shred the chicken and add it directly to the sauce, we like the elegance of serving the roast chicken breasts on top of the sauce and passing extra around in a gravy boat. http://www.gourmet.com/recipes/2000s/2009/05/chicken-in-chile-sauce
