Cream
sugar and butter, then add 2 egg yolks and cream them into the mixture. Then
add the flour and work it into the mixture.
Next, zest ½ a lemon (or more
if you want the dessert extra tart) and juice 1 and ½ lemons. Add the zest
and juice to the butter and sugar, stirring it together until well mixed. Then
add the milk and mix it well.
Beat the two egg whites until
stiff and fold the lemon/butter/sugar mixture into the egg whites.
Butter a baking dish (or smaller
ramekins) and pour the mixture in. Place the bowl(s) into a deep baking pan
that has hot water in the bottom and place in the preheated oven. Cook for 45
minutes (+ or -) until the top of the dessert is nicely browned. Remove the
pan from the oven, take the bowl(s) out of the hot water, let cool and then
serve.
