Key-nadian Twist On A Father’s Day Favorite

I really thought that I’d tried every Key lime dessert recipe known to man.  As I’ve mentioned in a previous post, my dad’s all-time favorite indulgence is Key lime pie, which I grew tired of making about fifteen Birthdays/Father’s Days ago.  Since then, I’ve found ways to incorporate all of those delicious Key lime pie components into many different dessert shapes and forms.  I truly believed that I’d done it all… every Key lime concoction on the planet.  But there was one region of the Earth that I missed… Canada.  Cana..DUH!

Originating from the Great White North, a Nanaimo bar is a layered dessert traditionally composed of a sometimes nutty, brownie-like layer, a custard or buttercream layer, and a chocolate layer.  There are many different versions of Nanaimo bars, leaving me with lots of options to incorporate all of the flavors of the Key lime pie.  I was sold.  As the Vancouver Canucks have demonstrated this season, Canada knows great hockey, just as my dad, a die-hard Red Wings fan, does.   And, as it turns out, Canada also knows a thing or two about dessert!

Upon grocery shopping for ingredients, I also stumbled upon a couple of products that I’d been previously unfamiliar with, pure Key lime extract and natural crystallized lime.  The extract allowed me to achieve a nice, strong lime flavor without having to add too much actual lime juice and watering down the custard.  And the crystallized lime also added an extra kick without ruining the consistency of the filling.  This is an issue I’ve dealt with in the past, having never wanted to sacrifice any of my dad’s favorite lime flavor but also not wanting to jeopardize the quality of the dessert.  Both of these great new products will be of great use to me for years to come as I continue to make Key lime confections for the world’s greatest dad.  Happy Father’s Day, Papa Lew!

Key-nadian Lime Pie Bars

Inspired by: Key Lime Pie

Adapted from “Nanaimo Bars,” The Daring Kitchen  and Parsley, Sage, Desserts and Line Drives

Graham Layer

½ cup unsalted butter              2/3 cup almond flour

3 tablespoons brown sugar     1/3 cup flaked coconut, finely ground in food processor

1 egg, lightly beaten                ¼ cup unsalted pistachios, finely ground in food processor

2 cups graham cracker crumbs

Prepare a double boiler fitted with a large glass bowl.  Melt the butter and brown sugar until the sugar has completely dissolved.  Pour a small amount of the melted butter-sugar into the dish containing the egg while whisking, bringing the egg slowly up to temperature without cooking and scrambling it.  Once the egg has been slightly warmed, pour it into the glass bowl with the remaining melted butter-sugar, stir, and continue to heat.  After the mixture is homogeneous and slightly thickened, remove the bowl from heat and stir in graham crumbs, almond flour, and ground coconut.

Key Lime Layer

3 egg yolks                                           ¼ cup cream cheese, softened

5 tablespoons granulated sugar          2 tablespoons custard powder*

3 tablespoons Key lime extract            1-2 cups confectioner’s sugar

zest and juice of 1 lime                        3 tablespoons heavy cream

1 tablespoon cornstarch

3½ tablespoons unsalted butter, cold

¼ cup unsalted butter, room temperature

-optional: crystallized lime, green/yellow gel food coloring

In a heavy-bottomed saucepan whisk together the egg yolks, granulated sugar, lime extract, juice, zest, and cornstarch.  Place over medium-low heat and continue to stir constantly with a wooden spoon.  Allow about 5-7 minutes for the mixture to thicken, and then remove it from heat and transfer it to a small bowl.  Constantly stirring, gradually mix in small pieces of the cold butter, allowing each piece to dissolve before adding the next piece.  Once all the butter has been added and the mixture is smooth and cooled, cover the bowl with plastic wrap, allowing the plastic wrap to sag into the bowl and cover the entire surface of the mixture so that it doesn’t develop a skin.  Allow mixture to set up in the refrigerator for 15-20 minutes.

When lime mixture has set, remove it from the refrigerator, peel away and discard the plastic wrap.  Set mixture aside, stirring occasionally, and allow it to come to room temperature.  In a large bowl, beat together the room temperature butter and cream cheese until thoroughly creamed.  Beat in the room temperature lime mixture and food coloring (if desired) until homogeneous.  Mix in the custard powder and gradually beat in the powdered sugar.  If an increase in lime flavor is desired, also beat in desired amount of crystallized lime (I used about 1½ teaspoons).  When desired flavor is reached, drizzle in heavy cream and whip until combined and fluffy.

*Vanilla instant pudding mix may be used here.

Chocolate Layer

2 ½  tablespoons unsalted butter

½ tablespoon heavy whipping cream

6 ounces white chocolate

In a heavy-bottomed saucepan over low heat, bring butter and cream to a simmer, whisking constantly to prevent it from scalding.  Prepare a double boiler fitted with a medium glass bowl containing the white chocolate and place it over medium heat.  Stir in the hot cream to the melting chocolate and continue to stir until fully melted.  Remove from heat.

Assembly

Line 8×8 pan with parchment paper, allowing the excess to drape over the sides  for easy dessert removal.  Press graham mixture into an even layer on the bottom of the lined pan.  Spoon on the lime layer and spread evenly across the entire surface of the graham layer.  Then, pour the warm, melted chocolate onto the top, evenly coating the dessert and reach all edges of the pan.  Let the dessert rest until chocolate has cooled and set before removing it from pan and slicing into bars.
