My father usually makes this on Christmas Eve because he believes the dish is more flavorful the next day. This, however, may be an excuse to not have to attend midnight church service. Also, note that at some time during the meal he will ask, "I wonder who else in this community is having shrimp curry for Christmas dinner?" Tradition has all four kids rolling their eyes and responding, "Just us, Dad." Later in the meal, Pop will say, "You know, I really think this is my best batch ever." All agree heartily and shout, "Merry Christmas!"
