Limes College Sutton is a bright, tangy lime curd tart with a buttery shortcrust pastry shell, inspired by the classic British bake-sale favorite. The name is a playful nod to the school-run fundraising tradition, but the recipe itself is a straightforward, reliable dessert that works every time. A silky, not-too-sweet lime curd sits in a crisp, golden crust, making it a refreshing end to any meal or a standout at a picnic.
Ingredients
- For the pastry: 1 ¼ cups (155 g) all-purpose flour, plus extra for dusting
- For the pastry: ¼ cup (50 g) granulated sugar
- For the pastry: ½ cup (115 g) cold unsalted butter, cubed
- For the pastry: 1 large egg yolk
- For the pastry: 2–3 tbsp (30–45 ml) ice-cold water
- For the filling: 4 large eggs
- For the filling: ¾ cup (150 g) granulated sugar
- For the filling: ½ cup (120 ml) fresh lime juice (about 4–5 limes)
- For the filling: 2 tsp lime zest (from 2 limes)
- For the filling: ½ cup (115 g) unsalted butter, melted and cooled
- For serving: powdered sugar, for dusting (optional)
Instructions
- Make the pastry: In a food processor, pulse the flour and sugar together. Add the cold butter and pulse until the mixture resembles coarse crumbs. Add the egg yolk and 2 tablespoons of ice water, pulsing until the dough just comes together. If it seems dry, add the remaining water, 1 teaspoon at a time. Turn the dough out onto a lightly floured surface, shape into a disk, wrap in plastic, and refrigerate for 30 minutes.
- Roll out the chilled dough on a floured surface to a 12-inch (30 cm) round. Ease it into a 9-inch (23 cm) tart pan with a removable bottom, pressing it into the corners. Trim the edges, then prick the bottom with a fork. Freeze for 15 minutes while you preheat the oven to 375°F (190°C).
- Line the frozen pastry with parchment paper and fill with pie weights or dried beans. Bake for 15 minutes, then remove the paper and weights and bake for another 5–7 minutes, until the crust looks dry and lightly golden. Set aside to cool slightly. Reduce the oven temperature to 325°F (165°C).
- Make the filling: In a medium bowl, whisk the eggs and sugar until well combined. Whisk in the lime juice, zest, and melted butter until smooth. The mixture will look a little curdled at first, but it will come together as you whisk.
- Pour the filling into the warm (not hot) pastry shell. Place the tart pan on a baking sheet to catch any spills. Bake for 25–30 minutes, until the filling is set around the edges but still slightly jiggly in the center. The internal temperature should reach 160°F (71°C) as the safe minimum for egg dishes, per USDA FSIS.
- Cool the tart completely on a wire rack, then refrigerate for at least 1 hour before serving. Dust with powdered sugar just before slicing.
Tips
- Substitutions: For a gluten-free version, use a 1:1 gluten-free flour blend in the pastry. The texture will be a bit more crumbly, but it will still hold together. You can also replace the lime with lemon or a mix of citrus for a different flavor.
- Storage: This tart keeps well in the fridge for up to 3 days. Cover it loosely with foil or plastic wrap to prevent the crust from becoming soggy.
- Common mistake: Overbaking the filling makes it rubbery. Always pull the tart out when the center still has a slight wobble – it will set as it cools. Also, be sure to chill the pastry before baking to prevent shrinking.
- Zest tip: Zest the limes before juicing them – it’s much easier. Use a microplane or fine grater, and avoid the white pith, which is bitter.
Serving Suggestions
Serve the tart chilled, straight from the fridge, with a dusting of powdered sugar. It pairs beautifully with a dollop of lightly sweetened whipped cream or a scoop of vanilla ice cream. For a brunch spread, offer it alongside fresh berries and a pot of Earl Grey tea.
Variations
- Meringue topping: For a lemon-meringue-style twist, top the baked tart with a layer of Swiss meringue and toast it with a kitchen torch.
- Ginger crust: Add 1 teaspoon of ground ginger to the pastry dough for a warm, spicy note that complements the lime.
- Coconut-lime: Replace 2 tablespoons of the lime juice with coconut milk and fold in ½ cup (40 g) of shredded coconut to the filling.
Storage and Reheating
Store leftover tart in the refrigerator, covered, for up to 3 days. It is best served cold, so no reheating is needed. If you prefer it slightly warm, you can reheat individual slices in a 300°F (150°C) oven for 5–7 minutes, but be aware the crust may soften. For longer storage, freeze the fully baked and cooled tart (without the powdered sugar) for up to 2 months. Thaw overnight in the refrigerator before serving.
Frequently Asked Questions
Can I use bottled lime juice? Fresh lime juice is strongly recommended for the best flavor. Bottled juice often has a flat taste and may contain preservatives that affect the set. If you must use bottled, choose a high-quality brand without added sugar.
Why did my curd separate or curdle? Curdling usually happens if the eggs are cooked too quickly or at too high a temperature. Whisk the filling well before baking, and always bake at the lower temperature (325°F/165°C) as directed. If the curd does separate, it may still taste fine, but the texture will be grainy.
Can I make this tart ahead of time? Yes, you can make the tart a day in advance. Bake and cool it completely, then refrigerate it uncovered for an hour, then cover once fully chilled. Add the powdered sugar just before serving.
How do I know when the tart is done? The filling should be set around the edges but still have a slight jiggle in the center. A food thermometer inserted into the center should read 160°F (71°C), the USDA FSIS safe minimum for egg dishes.
Can I use a regular pie dish instead of a tart pan? Yes, a 9-inch (23 cm) pie dish works, but the crust will be slightly thicker. You may need to increase the blind-baking time by a few minutes. The filling amount is the same.
What if my pastry shrinks during baking? Shrinking is usually caused by overworking the dough or not chilling it enough. Be sure to chill the dough for at least 30 minutes before rolling, and handle it as little as possible. If it still shrinks, press the edges back up while the crust is still warm.
