The first time I tried this classic dish was at a Peruvian restaurant in New York City's West Village - it immediately became one of my favorite dishes. Now that I live in Washington, DC, which has a great Peruvian community and lots of great restaurants, I can have it whenever I like. My favorite way, though, is to cook it at home. I've tried several recipes over the years, and by mixing and matching and editing and experimenting, this is what I've come up with. Just a quick note - "Gallina" means rooster, as this is what the traditional recipe was made with. I make mine with chicken, since it is more readily available. So technically this would be "Aji de Pollo." If you happen to have a rooster laying around, let me know how it goes!
