Ingredients for Gemma’s “The Whole Lemon” Tart

- 1 x recipe pie crust (store-bought or homemade)
- 1 medium lemon (about 4 1/2 oz/130g, washed thoroughly)
- 1 ½ cups (12oz/340g) sugar
- ½ cup (4oz/115g) butter, softened
- 4 large eggs
- 1 large egg yolk
- 2 tablespoons (½ oz/15g) cornstarch
- 3 tablespoons (1 ½ oz/42g) lemon juice (freshly squeezed)
- ¼ teaspoon salt
Step-by-Step Instructions
- Preheat the oven to 350°F (180°C).
- Prepare the crust: Roll out the pie crust and line a 9-inch tart pan with it. Line the crust with parchment paper and fill with pie weights (e.g., lentils or beans).
- Blind bake the crust for 20 minutes. Remove the weights and parchment, then bake for another 5-10 minutes to ensure the bottom is fully baked.
- Prepare the filling: Cut the lemon in half, then into quarters. Remove and discard any pits. Add the lemon, sugar, and butter to a food processor and blend until very smooth, about 4-5 minutes.
- Add remaining ingredients: To the food processor, add the eggs, egg yolk, cornstarch, lemon juice, and salt. Process until fully combined.
- Assemble the tart: Pour the filling into the pre-baked crust. Place the tart pan on a baking sheet and bake for 35-40 minutes, or until the filling is set but still slightly jiggly when tapped.
- Cool completely: Let the tart cool for at least 2 hours, or until it reaches room temperature.
- Serve: Slice and enjoy with freshly whipped cream. Store any leftovers, covered, in the refrigerator for up to 2 days.
Perfect Pairings: Serving Suggestions
This tart shines on its own, but a dollop of freshly whipped cream or a scoop of vanilla ice cream takes it to the next level. For a refreshing twist, garnish with a few raspberries or a sprinkle of lemon zest. Pair it with a cup of Earl Grey tea for a delightful afternoon treat.
Storage Secrets: Keeping It Fresh
Store your tart, covered, in the refrigerator for up to 2 days. If you need to keep it longer, wrap individual slices in plastic wrap and freeze for up to 1 month. Thaw in the fridge overnight and let it come to room temperature before serving for the best texture.
Time-Saving Tips for Busy Bakers
To save time, use a store-bought pie crust instead of making your own. You can also prep the lemon filling a day ahead and store it in the fridge—just give it a quick blend before pouring it into the crust. If you’re short on pie weights, uncooked rice works just as well as lentils or beans.
Recipe Variations: Make It Your Own
For a tangier twist, add an extra tablespoon of lemon juice or a teaspoon of lemon zest to the filling. If you’re feeling adventurous, swap the lemon for a lime or orange for a completely different flavor profile. You can also add a layer of raspberry jam to the crust before pouring in the filling for a fruity surprise.
Equipment Essentials: What You’ll Need
Make sure you have a 9-inch tart pan with a removable bottom for easy slicing. A food processor is key for blending the lemon filling until smooth. Don’t forget parchment paper and pie weights (or lentils/beans) for blind baking the crust to perfection.
