This hearty chicken and potato stew makes a wonderful comfort food. The ají panca chili gives the stew a rich, complex, smoky and sweet flavor without a lot of heat, but you can always add more if you want a little spice. If you can’t find ají panca chili, ancho powder or chipotle powder can be used, though chipotle is quite a lot hotter so you may want to use just a teaspoon or less. You can use frozen mixed vegetables in place of the carrots and peas if you like, adding them near the end.
