Ingredients

1/4 cup safflower oil

3 cups diced white onion (from 1 large onion)

3 fresh poblano chiles, seeds and ribs removed, diced (3 cups)

1 tablespoon coriander seeds, toasted and coarsely ground

Coarse salt

1/4 cup fresh lime juice (from 2 to 3 limes)

4 ounces cream cheese, room temperature

1/2 cup sour cream

Cayenne pepper, for sprinkling

Cut-up cucumbers, jicama, and radishes, or chips, for serving

Preparation

Heat oil in a large skillet over medium heat. Add onion, chiles, coriander, and 1 teaspoon salt. Saute, stirring occasionally, until onion and chiles are tender and caramelized, 25 to 30 minutes. Let cool completely.

Stir together lime juice, cream cheese, and sour cream in a large bowl, using a rubber spatula, until smooth. Stir in onion mixture. Season with salt if necessary. Refrigerate at least 1 hour and up to 1 day. Sprinkle with cayenne. Serve with cut-up vegetables or chips.
