Whip 2 whole eggs, 2 eggs yolks and sugar until creamy. Add vanilla extract and lemon juice. Pour in hot milk and stir well. Fold beaten egg whites into the mixture.
Pour the filling into unbaked pie crust (don't prick the dough with a fork or the filling will leak out). Bake for 30-40 minutes or until firm. Allow Filipino Egg Pie to cool before serving.
