Lemon Snow

1 1/4 cups sugar
1/4 cup cornstarch
1 1/4 cups water
3 eggs, separated (yolks, slightly beaten)
1/4 cup lemon juice
1 tbsp butter

Combine sugar and cornstarch in a saucepan. Add the water gradually, stir until smooth.
Cook over medium heat, stirring constantly, until mixture thickens. Remove from heat.
Stir small amount of cooked mixture into beaten egg yolks. Add egg mixture to remaining cooked mixture in saucepan.
Return to heat and bring to boil, careful not to let the mixture burn on the bottom of the pan. Remove from heat and stir in lemon juice and the butter.
Beat egg whites until they form soft peaks and fold into filling mixture. Cover and refrigerate until set.

I emailed mom to ask her for this recipe, and this was the note at the bottom when she emailed the recipe back: Try to remove the "white umbicks" from the eggs lest you find a lump in your pudding when it is your mouth!!!!!

( You can substitute the lemon juice for 1/4 cup of passion fruit juice.)
