Method:
Preheat oven to 175'C (350'F). In a large bowl, cream butter. Add sugar, flour salt, lemon juice and rind. In a separate bowl, beat egg yolks; stir in milk. Slowly add second mixture to first mixture. Beat egg whites until stiff; gently fold into mixture. Pour into ramekins or individual soufflé dishes and place in pan of hot water. Bake in "moderate" oven (175'C) for 45 minutes. You will have a layer of lemon custard, with gorgeous, lightly browned sponge on top. Let cool a bit. Turn out and serve with whipped cream, or serve still in the dish. You can also bake this in one large soufflé dish. Aunt Mariah likes to garnish with a thin slice of lemon.
