This is made with canned apricots. Don't let that scare you away. It is delicious! My DH (who hates fruit in main dishes) likes this dish. Oh well! I've never added the dried, chopped apricots and it tastes just fine.
Gently poach the chicken in a covered heavy bottomed pan in the liquid for about 10 minutes. Remove and let rest.
Add the onions and oil to the pan and increase the heat to medium. The pan will sizzle as the liquid reduces and the onions saute. (This may take awhile.) Stir in the curry powder and drained, canned apricots. It will form a thick paste.
Cool a little and then use a blender to puree the apricots with the mayo and sour cream to yield a creamy, vibrant yellow sauce.
Slice the reserved chicken and add to the sauce (in a serving bowl), then finish by adding chopped dried apricots.
