A famous dish from the famous ‘21’ Club. It is good. It is cubed chicken in a very flavorful béchamel sauce served over toast, waffles, rice or baked potato.
Melt butter over medium heat. Whisk in flour, cook, whisking for 2 minutes. Stir in hot milk and continue to whisk 15 minutes till mixture thickens. Add seasonings, cover saucepan and place in 300* oven till thick and fluffy – 1½ hrs. Correct seasoning (1 cup sauce).
HASH: Whisk béchamel and cream over medium heat till fluffy and mix well. Reduce heat and stir in chicken. Cook till heated through (5 minutes). Stir in egg yolks.
Note: I made the sauce ahead of time all the way through to (and including) stirring in the egg yolks, leaving out the chicken. When I was ready to serve it, I added the chicken and heated it.
