Dressing:
2 cups mayonnaise
1/2 cup commercial chutney
3 tablespoons mild curry powder
Sandwich:
6 bone-in chicken breasts
Kosher salt and freshly ground black pepper
1/2 cup coarsely chopped walnuts
1/2 cup dark raisins
3/4 cups finely chopped celery
4 croissants
To make the dressing: Combine the mayonnaise with the chutney and the curry powder in a small bowl. Mix well and set aside.
To prepare the sandwiches: Season the chicken breasts with salt and pepper then put them in a large skillet. Add water to cover. Put a lid on the skillet and simmer the chicken until it is cooked through, about 20 minutes. Remove the chicken from the poaching liquid and refrigerate for at least 1 hour. When the chicken is chilled remove the skin and cut the meat from the bones. Dice the meat and place it in a large bowl. Add the walnuts, raisins, and celery and mix well. Moisten the salad with the curry dressing. Cut the croissants in half. Fill each with chicken salad and serve.
