Ingredients (2 Servings)
Shared Ingredients:
- 3 large eggs
- 1/2 cup fresh lemon juice (about 2-3 lemons)
- Zest of 2 lemons
- 1/4 cup heavy cream
Traditional Version
- 1 cup all-purpose flour
- 1/2 cup unsalted butter, softened
- 1/4 cup granulated sugar
- 1/4 tsp salt
- 2 tbsp cold water
Keto Version
- 1 cup almond flour
- 1/2 cup unsalted butter, softened
- 1/4 cup erythritol (or another keto-friendly sweetener)
- 1/4 tsp salt
- 2 tbsp cold water
Instructions
1. Prepare the Crust:
-
Traditional Version: In a mixing bowl, combine all-purpose flour, softened butter, sugar, and salt. Use your fingertips to mix until you achieve a sandy texture. Add cold water, a tablespoon at a time, and mix until the dough forms. Wrap it in plastic wrap and refrigerate for at least 30 minutes.
- Keto Version: In a mixing bowl, combine almond flour, softened butter, erythritol, and salt. Mix until the mixture resembles breadcrumbs. Add cold water as needed to bring the dough together. After forming a ball, wrap it in plastic wrap and refrigerate for 30 minutes.
2. Pre-Bake the Crust:
Preheat your oven to 350°F (175°C). Roll out the chilled dough on a floured surface (or a silicone mat for keto) to fit your tart pan. Gently press it into the pan, trimming the excess. Prick the base with a fork and bake in the preheated oven for 15-20 minutes until golden brown. Allow it to cool completely.
3. Make the Filling:
In a mixing bowl, whisk together eggs, lemon juice, lemon zest, and heavy cream until smooth. For the traditional version, add sugar. For the keto version, ensure the erythritol is fully dissolved.
4. Bake the Tart:
Pour the filling into the cooled crust. Bake in the oven for 20-25 minutes until the filling is just set but still slightly wobbly in the center. Remove and let it cool at room temperature, then refrigerate for at least an hour before serving.
5. Serve:
Slice the tart and serve chilled, optionally garnished with whipped cream or fresh berries for a burst of color and flavor.
What Does It Pair Well With?
-
Traditional Pairings: Pair your Tarte au Citron with a glass of chilled Sancerre or Earl Grey tea. The citrus notes will elevate your tasting experience, almost like a refreshing breeze on a warm day.
- Keto-Friendly Pairings: Enjoy a slice with a cup of herbal tea or sparkling water infused with mint and cucumber. The lightness of these beverages balances the tartness beautifully, keeping your keto journey delightful.
What is the Shelf Life?
Tarte au Citron is best enjoyed fresh, but it can be stored in the refrigerator for up to 3 days in an airtight container. To keep it fresh, cover it with plastic wrap to prevent drying. Both versions can be frozen for up to a month; just ensure it’s well-wrapped to avoid freezer burn. When ready to enjoy, thaw overnight in the refrigerator and serve cold.
Alternative Cooking Methods
-
Oven: The classic method remains the best for achieving that perfect golden crust.
- Air Fryer: Preheat your air fryer to 300°F (150°C) and bake the tart in a suitable dish for 15-20 minutes. This method can give a wonderfully crunchy crust while saving time.
Conclusion: Traditional and Keto Versions
Whether you indulge in the traditional Tarte au Citron with its buttery crust or the keto version that satisfies your low-carb cravings, both variations promise a symphony of flavor with every bite. The zesty lemon filling combined with the delicate crust creates a harmonious experience that captivates the taste buds. As you savor this creamy delight, remember it’s not just a dessert; it’s a moment to celebrate the art of French pastry and the joy of cooking.
