...three French hens.
I know this is a real stretch, but we had a houseful of family and friends tonight and neither three roasted chickens nor coq au vin were going to be a good choice for the menu. It was Beef Enchiladas, yellow rice and Mexican slaw. But, for dessert...Creme Brulee, AKA Three French Hens (there are three egg yolks in the recipe).
The three French hens in the song represent the charities Faith, Hope and Love.
