I'll share with you one of the simplest and yummiest dessert recipes that I know --- Lemon Pie. One of the things that makes it so easy is that I choose to use a graham cracker crust instead of making my own. The graham cracker crust just seems like a better match for this filling.
1 cup sugar
3 TBSP cornstarch
1 cup milk
1/4 cup lemon juice
3 egg yolks, slightly beaten
1/3 cup butter
1 TBSP grated lemon peel
1 cup sour cream
Combine sugar and cornstarch in a saucepan. Stir in milk, lemon juice and egg yolks. Cook over medium hear, stirring constantly, until thick. This will take about 10 minutes, but it will feel longer!
Remove from heat. Stir in butter until melted. Add lemon peel. Cool. Fold in sour cream. Spoon into graham cracker crust. Refrigerate.
Whenever I make this pie, I also make a batch of macaroons with the 3 egg whites. How's that for efficient?
