This shop is part of a social shopper marketing insight campaign with Pollinate Media Group® and Post Pebbles, but all my opinions are my own. 

A couple of days ago I had grown so tired of gray, gloomy weather that I got to the point that I had to create something that would be like a taste of Spring.   For me, there is nothing more cheerful and “sunny” than lemons, so a lemon pie was in order.  And as the title of this post implies, one made with Grape-Nuts.

Did you know that Grape-Nuts has been used for years in pie crusts?  Grape-Nuts itself has been around for more than 100 years.

I headed to Walgreens and bought a box so that I could get started making my pie. 

A Tidbit About the Name

Grape-Nuts actually contains neither grapes nor nuts. It’s made from natural wheat and barley. So, why is it called Grape-Nuts? As with many great emblems in history, there are two versions of the story. One says that Mr. Post believed glucose, which he called “grape sugar,” formed during the baking process. This, combined with the nutty flavor of the cereal, is said to have inspired its name. Another explanation claims that the cereal got its name from its resemblance to grape seeds, or grape “nuts.”

Grape Nuts and a food processor

Back to the pie.  This pie is really easy to make.  Just take a cup of Grape-Nuts and place it in your food processor.  Pulse until it becomes fine and crumbly.  Don’t worry about having some nutty bits left behind.  Next, you add 1/4 cup of thawed apple juice concentrate and pulse some more until the cereal is moist.

Pie Crust made with Grape Nuts

Spread the cereal out in a pie pan that has been lightly sprayed with non-stick spray.  Be sure to cover the entire bottom and about halfway up the sides.  Now it gets baked for only 5 minutes in an oven that has been preheated to 350 degrees.

 Lemon Pie filling in a bowl

While the crust is baking, combine a can of sweetened condensed milk, 2 eggs, the zest from one lemon and the juice from three lemons.  Pour this creamy mixture into the prebaked pie crust and bake for another 15 minutes.  Allow the pie to cool and then refrigerate it for a couple of hours.
