When used in the famously flavor-packed stew, the gently simmered greens are added to the pot at the last minute, so that they won’t overcook and lose their deep-green color. An array of traditional ingredients and spices precedes them, most notably onion, okra, and garlic, as well as coconut milk, chiles, and yams or green bananas; depending on the region, these will be joined by a little salt pork, salt cod, beef, or crabmeat.
