Another one I like from Bon Appetitpoblano potato salad
Bon AppÃ©tit | July 1998 Potato salad with a southwestern kick‑the perfect partner for grilled flank steak, chicken or red snapper seasoned with cumin.
Serves 4 to 6.
3 medium poblano chilies (about 9 ounces total) 2 pounds small red-skinned potatoes, unpeeled, each cut into 6 wedges
6 medium tomatillos (about 7 ounces), husked, cut into1/2-inch pieces
1 1/4 cups chopped green onions
1/4 cup chopped fresh cilantro
1 cup sour cream
3 tablespoons fresh lime juice
1 3/4 teaspoons ground cumin
Fresh cilantro sprigs
Char chilies over gas flame or in broiler until blackened on all sides. Enclose in paper bag; let stand 10 minutes. Peel and seed chilies. Cut chilies into 1/2-inch pieces. Transfer to large bowl. Place potatoes on steamer rack set over boiling water in pot. Cover and steam until potatoes are just tender, about 10 minutes. Cool. Transfer to bowl with chilies. Mix in tomatillos, green onions and chopped cilantro.
Whisk sour cream, lime juice and cumin in small bowl to blend. Add to potato mixture and toss to coat. Season generously with salt and pepper. (Can be prepared 6 hours ahead. Cover and refrigerate. Let stand at room temperature 30 minutes before serving.)
Mound potato salad on platter. Garnish with cilantro sprigs and serve.
