Directions
<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Begin with the graham cracker crust. Preheat your oven to 180°C. In a food processor, pulse the graham crackers into fine crumbs. If you don't have a food processor, place crackers in a sealed bag and crush with a rolling pin. Transfer crumbs to a bowl and mix in sugar and salt, then pour in melted butter. Stir until the mixture resembles wet sand and holds together when pressed.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Press the crumb mixture firmly and evenly into your pie dish, creating a compact layer on the bottom and up the sides. Use the back of a measuring cup to help pack it down firmly - this prevents a crumbly crust later. Bake for 8-10 minutes until lightly golden and fragrant. The brief baking time toasts the crumbs and helps set the butter, creating a sturdier base. Cool completely on a wire rack.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>For the root beer filling, pour the root beer into a medium saucepan and bring to a simmer over medium heat. Allow it to reduce to about 175ml (this concentrates the flavor significantly). This should take about 10-12 minutes of gentle simmering. Remove from heat and let cool slightly.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>In a medium bowl, whisk together sugar and cornstarch. Add egg yolks and whisk until smooth and pale yellow. Gradually whisk in the milk until fully incorporated. This pre-mixing helps prevent lumps when added to the hot liquid.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Slowly pour the egg mixture into the reduced root beer, whisking constantly. Return the saucepan to medium heat and cook, whisking continuously, until the mixture thickens and begins to bubble. Once it bubbles, continue cooking for 1 minute more (this ensures the cornstarch is fully activated). The mixture should coat the back of a spoon and leave a clear path when you run your finger through it.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Remove from heat and strain through a fine-mesh sieve into a clean bowl to remove any lumps or bits of cooked egg. Immediately whisk in the butter, root beer concentrate, vanilla extract, and salt until smooth. The heat of the pudding will melt the butter, adding richness and a silky texture to your filling.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Press a piece of plastic wrap directly onto the surface of the filling (this prevents a skin from forming) and allow it to cool for 30 minutes at room temperature. Then refrigerate for at least 4 hours or overnight until completely chilled and set. Patience here is crucial - rushing this step could result in a filling that's too soft to slice cleanly.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>When ready to serve, prepare the vanilla cream topping. In a chilled bowl, combine cold heavy cream, powdered sugar, and vanilla extract. Using an electric mixer, beat on medium-low speed until small bubbles form, then increase to medium-high and whip until stiff peaks form. Watch carefully - overbeating will turn your cream grainy or buttery.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Gently spread or pipe the whipped cream over the chilled filling, creating decorative swirls if desired. The contrast between the caramel-colored filling and white cream mimics the classic root beer float appearance. For the complete root beer float experience, garnish with chocolate shavings and maraschino cherries if using.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>For the cleanest slices, chill the completed pie for 1 hour before serving. Use a sharp knife dipped in hot water and wiped clean between cuts. Store any leftovers covered in the refrigerator for up to 3 days, though the crust will gradually soften over time.</li></ol>
