For this multinational salad, strips of cold poached chicken are combined with pickly-crisp strips of blanched jícama, then drizzled with a light, sweet peanut sauce.
In a heavy pot that will hold chicken in one layer, combine water, ginger, celery, 2 scallions (sliced), and ½ teaspoon salt. Boil 5 minutes covered. Add chicken pieces and return to a bare simmer.
Cover, turn off heat, and let stand 1 hour. Place chicken in a dish and let cool. Remove skin and bones, then cover and refrigerate. Strain, reserve, and refrigerate
