Salt; I usually leave it out since the w. sauce adds enough sodium for me!
die Zubereitung:
In saucepan, melt butter, blend in four, gradually add milk, stirring until smooth. Sook & stir until thickened; add cheese (& salt), the W. sauce. When cheese is melted, remove from heat & cool. In a large bowl beat the egg yolks, gradually stir in cheese sauce. In separate bowl beat egg white until they stand in soft peaks. Gently fold into cheese mixture. Turn into a 2-quart, straight sided casserole or souffle dish. Place in a pan in 1" of hot water. Bake in preheated oven 1 hour at 325 degrees (this depends a lot on your oven - take a look at it at 45 mins.)
