Lemon Meringue Tart Made With Condensed Milk: A Taste of Home

The scent of lemon and toasted meringue always transports me back to my childhood summers. I can almost feel the warmth of the sun on my skin, hear the cicadas buzzing in the trees, and see my grandmother’s hands, dusted with flour, carefully crimping the edges of a pie crust. This Lemon Meringue Tart, adapted from her well-worn recipe, is more than just a dessert; it’s a tangible piece of family history, a sweet reminder of simpler times and enduring love.

Recipe Overview

• Prep Time: 30 minutes
• Cook Time: 1 hour
• Total Time: Overnight (including cooling time)
• Servings: 8-12
• Yield: 1 tart
• Dietary Type: Not suitable for dairy-free or gluten-free diets

Ingredients

For the Crust:

• 200g plain sweet biscuit crumbs (approximately one 200g packet), such as Tennis Biscuits (note: these contain coconut)
• 125g butter, melted

For the Filling:

• 6 eggs, separated
• 380g (1 can) condensed milk
• 1 cup lemon juice (freshly squeezed is best!)

For the Meringue:

• ¾ cup caster sugar

Equipment Needed

• Fluted pie dish
• Mixing bowls
• Electric mixer (handheld or stand mixer)
• Measuring cups and spoons
• Spatula
• Piping bag (optional, for decorative meringue)

Instructions

1. Preheat your oven to a low temperature of 120°C (250°F). This low and slow baking is key to preventing the meringue from cracking.

2. Prepare the Biscuit Base: Crush the plain sweet biscuits into fine crumbs. You can use a food processor for this, or simply place the biscuits in a ziplock bag and crush them with a rolling pin. Melt the butter in a saucepan or microwave.

3. Combine Crust Ingredients: In a mixing bowl, combine the crushed biscuit crumbs and melted butter. Mix thoroughly until the crumbs are evenly coated with butter.

4. Press into Pie Dish: Press the biscuit mixture firmly into the bottom and up the sides of a fluted pie dish. Use the back of a spoon or your fingers to create a smooth, even crust.

5. Chill the Crust: Place the prepared crust in the refrigerator to chill while you make the filling. This will help it set and prevent it from becoming soggy during baking.

6. Separate the Eggs: Carefully separate the eggs, placing the egg yolks in one mixing bowl and the egg whites in another. Ensure no yolk gets into the whites, as this will prevent them from whipping properly.

7. Prepare the Filling: Beat the egg yolks with an electric mixer until they are light and creamy. This will incorporate air and create a smoother filling.

8. Add Condensed Milk: Gradually add the condensed milk to the beaten egg yolks, mixing well after each addition. Make sure the condensed milk is fully incorporated for a smooth, homogenous mixture.

9. Add Lemon Juice: Slowly add the lemon juice to the condensed milk mixture, a little at a time, mixing well after each addition. The mixture will thicken as the lemon juice reacts with the condensed milk.

10. Pour Filling into Crust: Remove the chilled biscuit base from the refrigerator and pour the lemon filling into the prepared crust. Spread the filling evenly to the edges.

11. Prepare the Meringue: In the bowl with the egg whites, beat the egg whites with an electric mixer until soft peaks form. This means the whites hold their shape but the tips droop slightly.

12. Add Sugar Gradually: Gradually add the caster sugar to the egg whites, a little at a time, while continuing to beat. Beat until stiff peaks form. This means the whites are glossy and hold their shape firmly when the beaters are lifted. Be careful not to overbeat, as this can make the meringue dry.

13. Pipe or Spread Meringue: You can either pipe rosettes of meringue onto the filling using a piping bag fitted with a decorative tip, or simply spread the meringue evenly over the filling using a spatula. Make sure the filling is completely covered with the meringue to seal it and prevent it from weeping.

14. Bake: Place the tart in the preheated oven and bake for one hour. The meringue should be lightly golden brown.

15. Crucial Cooling Step: Turn off the oven and leave the tart in the oven with the door closed overnight (or for at least 8 hours). This slow cooling process is essential for preventing the meringue from shrinking and cracking. Do not be tempted to open the oven door during this time! The residual heat will gently set the meringue.

16. Remove and Chill: The tart should only be taken out of the oven the following morning (or after the cooling period). Store the tart in the refrigerator until ready to serve.

Expert Tips & Tricks

• Use room temperature eggs for the meringue. They whip up to a greater volume than cold eggs.
• A pinch of cream of tartar added to the egg whites can help stabilize the meringue and prevent it from weeping. Use about ⅛ teaspoon.
• Avoid overbaking the meringue. It should be lightly golden brown, not dark brown, as this can make it brittle and dry.
• For a more intense lemon flavor, add a teaspoon of lemon zest to the filling.
• If your meringue starts to brown too quickly, you can tent it with foil to prevent it from burning.
• Don’t skip the overnight cooling! This is the most important step for a perfect meringue.
• If you are concerned about the safety of leaving the tart in the oven overnight due to potential bacteria growth from the egg filling, you can adjust the baking time. Bake until the filling is set and then cool gradually in the turned-off oven for several hours before refrigerating. However, the original recipe is designed with the slow cooling process in mind.

Serving & Storage Suggestions

Serve the Lemon Meringue Tart chilled, straight from the refrigerator. A dusting of powdered sugar or a few fresh lemon slices can add a beautiful finishing touch.

Store leftover tart in the refrigerator for up to 3 days. The meringue may soften slightly over time, but the flavor will still be delicious. While you can freeze the tart, the meringue texture will be significantly affected upon thawing, so it’s best enjoyed fresh.

FAQs (Frequently Asked Questions)

Q: Why is the tart left in the oven overnight?
A: Leaving the tart in the oven to cool slowly prevents the meringue from shrinking, cracking, and weeping. This gentle cooling process allows the meringue to set properly and maintain its structure.

Q: Can I use bottled lemon juice instead of fresh?
A: Freshly squeezed lemon juice is recommended for the best flavor, but bottled lemon juice can be used in a pinch. However, the flavor will not be as bright and vibrant.

Q: What if my meringue is weeping?
A: Weeping can be caused by underbeaten egg whites, overbaking, or high humidity. Ensure you beat the egg whites to stiff peaks and avoid overbaking. Also, ensure the filling is completely covered with meringue.

Q: Can I make this tart ahead of time?
A: Yes, you can make the tart a day or two in advance and store it in the refrigerator. However, the meringue may soften slightly over time.

Q: What kind of biscuits are best for the crust?
A: Plain sweet biscuits like Tennis Biscuits (though these contain coconut) work well. Avoid ginger biscuits, but digestive biscuits or shortbread cookies are also good options. Adjust butter accordingly.
