Morton’s Irresistible Key Lime Pie

My earliest memory of Key Lime Pie isn’t from the Florida Keys, but from a small bakery tucked away in my childhood neighborhood. The tangy, creamy filling, paired with the simple graham cracker crust, was sunshine on a plate. It was the dessert I always requested for my birthday, and the taste still transports me back to those carefree days. To this day, a good Key Lime Pie is my go-to dessert when I need a little bit of that sunshine in my life.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 30 minutes
• Total Time: 45 minutes
• Servings: 8
• Yield: 1 pie
• Dietary Type: Not Gluten-Free

Ingredients

• 1 graham cracker pie crust
• 1 ounce egg white (approximately one egg)
• 2 (14 ounce) cans sweetened condensed milk
• 6 tablespoons sugar
• 1 cup pasteurized egg yolk
• 8 ounces Realime brand lime juice
• 1 pint whipping cream
• 2 1/2 tablespoons powdered sugar
• 1 lime, if desired (for garnish)

Equipment Needed

• Oven
• Mixing bowl
• Whisk
• Electric mixer
• Refrigerator
• Measuring cups and spoons

Instructions

1. Preheat your oven to 375 degrees Fahrenheit.
2. Remove the plastic cover from the graham cracker pie crust.
3. In a small bowl, lightly beat the egg white. Brush the inside of the crust with the beaten egg white. This helps to seal the crust and prevent it from becoming soggy.
4. Bake the crust for 5 minutes. This pre-baking helps the crust to set up.
5. Remove the crust from the oven and set aside to cool slightly. Leave the oven on.
6. In a large mixing bowl, combine the sweetened condensed milk, sugar, pasteurized egg yolks, and lime juice.
7. Using a whisk, whip the ingredients together by hand until the mixture is smooth and the sugar has completely dissolved. Make sure to scrape the sides and bottom of the bowl to ensure everything is well combined.
8. Pour the lime mixture into the pre-baked graham cracker pie crust. Be careful to fill it to the rim without spilling over the edge.
9. Place the pie in the preheated oven and bake for approximately 30 minutes, or until the center is firm. A slight jiggle is okay, but it should not be liquid.
10. Remove the pie from the oven and carefully place it in the refrigerator to chill completely. This will take several hours, ideally overnight.
11. While the pie is chilling, prepare the whipped cream. In a separate mixing bowl, combine the whipping cream and powdered sugar.
12. Use an electric mixer to whip the cream on high speed until very stiff peaks form. Be careful not to overwhip, or the cream will turn grainy.
13. Once the pie is thoroughly chilled, remove it from the refrigerator.
14. Serve with a generous dollop of the freshly whipped cream.
15. Garnish with a slice of lime, if desired, for a pop of color and added visual appeal.

Expert Tips & Tricks

• For a more intense lime flavor, consider adding the zest of one lime to the filling mixture. Be sure to zest the lime before juicing it.
• If you don’t have pasteurized egg yolks, you can pasteurize them yourself by gently heating them with the sugar and milk over a double boiler, stirring constantly, until the mixture reaches 160°F. Then, remove from heat and proceed with the recipe.
• To prevent the graham cracker crust from burning during pre-baking, you can use a pie shield or cover the edges with foil.
• When whisking the filling, make sure the sugar is fully dissolved before pouring it into the crust. Undissolved sugar can result in a grainy texture.
• For a smoother whipped cream, make sure both the bowl and the beaters are chilled before you begin.
• If your pie crust is pre-made and seems a little bland, you can brush it with melted butter before pre-baking for added richness.
• If you prefer a less sweet pie, you can reduce the amount of sugar in the filling by a tablespoon or two.
• To easily slice the chilled pie, run a long, thin knife under hot water and wipe it dry before each cut. This will help prevent the filling from sticking to the knife.

Serving & Storage Suggestions

Key Lime Pie is best served chilled, straight from the refrigerator. The cool, creamy filling and crisp crust make it a refreshing dessert, especially on a warm day.

Leftover pie should be stored in the refrigerator, covered, for up to 3 days. The lime juice may slightly break down the crust over time, so it’s best enjoyed sooner rather than later. While it can be frozen, the texture of the filling may change slightly upon thawing, so it’s not recommended. The whipped cream topping is best added just before serving, as it can deflate over time.

• Dairy-Free: Substitute the whipping cream with a dairy-free alternative like coconut whipped cream.
• Lime Variety: While Realime brand lime juice is specified, fresh Key lime juice can be used. The tartness and intensity of the lime flavor may vary, so adjust the amount of sugar to taste.
• Crust Options: Try a shortbread crust or even a crushed vanilla wafer crust for a different flavor profile.
• Tropical Twist: Add a layer of mango or pineapple puree to the bottom of the crust before pouring in the lime filling for a tropical twist.

FAQs (Frequently Asked Questions)

Q: Can I use bottled lime juice instead of fresh lime juice?
A: Yes, this recipe specifies using Realime brand lime juice. While fresh lime juice can be used, the taste and tartness might be slightly different, so you may need to adjust the sugar accordingly.

Q: Why do I need to brush the crust with egg white before baking?
A: Brushing the crust with egg white creates a moisture barrier that helps prevent the crust from becoming soggy when the lime filling is added.

Q: How can I tell when the pie is done baking?
A: The center of the pie should be firm but still have a slight jiggle. If it is completely firm, it may be overbaked.

Q: Can I make this pie ahead of time?
A: Yes, Key Lime Pie is a great make-ahead dessert. It needs to chill in the refrigerator for several hours to set properly, so making it the day before serving is ideal.

Q: My whipped cream always seems to deflate. What am I doing wrong?
A: Make sure your whipping cream and bowl are very cold before whipping. Also, avoid overwhipping, as this can cause the cream to separate.
