This pie is made with bottled lemon juice. I've never tried it with fresh. Bottled juices usually have added lemon oil and lemon essence. I use the Pompeii Lemon Juice that comes in the little yellow round ball.
It's really a good ice box pie.
Preheat oven to 325°. In mixing bowl, beat egg yolks until smooth. Gradually blend in the condensed milk and lemon juice. Beat slowly until smooth. Pour into prepared pie crust.
Bake for 30 minutes. Remove from oven and let cool at room temperature for 1 hour. Chill in refrigerator at least 2 hours or until serving time. Top with cool whip or whipped cream. Refrigerate leftovers.
