Mexican Achiote Chicken Soup with Caramelized Onion

About This Recipe

Saffron isn't part of the traditional Mexican pantry, but achiote paste — made from ground annatto seeds — plays a similar role in coloring dishes a deep, warm gold, and it's a genuinely Mexican ingredient with roots in Yucatecan cooking. This soup uses achiote to tint and flavor a chicken broth, building depth with a base of slow-cooked, deeply caramelized onions rather than a quick sauté. The onions need real time on the stove, cooked low and slow until they turn a deep amber and taste almost sweet, which forms the backbone of the broth's flavor before the chicken and achiote paste go in. Achiote paste, usually sold as a brick and often blended with citrus juice and garlic, dissolves into the broth to give it both its color and a subtle earthy, slightly peppery flavor distinct from the ingredients most people associate with Mexican cooking. Finished with a squeeze of lime and a handful of cilantro, this soup sits somewhere between a caldo de pollo and a Yucatecan-style broth, built on real Mexican ingredients even though its combination isn't a single named traditional dish.
