Lobster tail pastries — known in Italy as aragostine — are hand-shaped, layered pastries filled with a ricotta-based cream. This version uses fresh lemon and orange zest to keep the filling bright rather than heavy. They take about two hours start to finish, but they package and travel well, which makes them worth the effort.
The short version of why this works
Two things determine whether these pastries succeed or fail. First, the butter must stay cold throughout mixing — warm butter blends into the flour instead of staying in distinct pieces, and those pieces are what create flaky layers as the pastry bakes. Work quickly and put the dough back in the fridge if your kitchen is warm. Second, sealing the edges firmly with a fork is not optional. The citrus cream is wet enough that a loose seal will blow open in a 400°F oven, leaving you with filling that has leaked out and burned onto the pan. Press the fork down hard and run it around the full edge twice if you’re unsure.
Troubleshooting
- Pastry is tough, not flaky: The dough was overworked. Once the liquid is added, mix only until the dough just comes together — a few dry-looking streaks are fine. Overworking develops gluten and toughens the texture.
- Filling leaks during baking: Either the edges weren’t sealed well enough, or too much filling was piped in. Keep the cream line narrow — about a tablespoon per pastry — and leave at least half an inch of bare dough around the edge before sealing.
- Bottoms are pale and soft while tops are golden: Move the baking sheet to a lower oven rack for the last five minutes. Pale bottoms usually mean the heat isn’t reaching the underside fast enough; a lower rack fixes this without overbrowning the tops.
- Cream filling is watery after mixing: Fresh ricotta varies in moisture content. If your mixture looks loose, drain the ricotta in a fine mesh strainer for 20–30 minutes before combining it with the other filling ingredients.
- Pastries soften too quickly after cooling: Humidity is usually the culprit. Once fully cooled, layer them between sheets of parchment in an airtight tin rather than stacking them directly — skip the garnish of powdered sugar until just before serving or gifting, since it absorbs moisture and turns sticky fast.
Sweet Lobster Tail Pastry with Citrus Cream
Equipment
- Oven
- Rolling pin
- Stand mixer or hand mixer
- Baking Sheets
- Pastry brush
- Piping bag
Ingredients
For the Pastry Dough:
- 2 ¼ cups all-purpose flour sifted
- ¼ cup granulated sugar
- ½ teaspoon salt
- ½ cup unsalted butter cold and cubed
- 1 large egg beaten
- â…“ cup cold water
For the Citrus Cream:
- 1 cup ricotta cheese fresh
- ½ cup powdered sugar plus extra for dusting
- 1 teaspoon vanilla extract
- 1 tablespoon lemon zest freshly grated
- 1 tablespoon orange zest freshly grated
- 2 tablespoons orange juice freshly squeezed
Instructions
Prepare the Pastry Dough:
- In a large mixing bowl, combine the flour, sugar, and salt. Add the cold butter and use your fingers to rub the butter into the flour until the mixture resembles coarse crumbs.
- Whisk together the egg and water, then gradually add to the flour mixture, stirring until the dough begins to come together. Form the dough into a disk, wrap in plastic wrap, and refrigerate for at least 30 minutes.
Prepare the Citrus Cream:
- In a bowl, mix the ricotta, powdered sugar, vanilla extract, lemon zest, orange zest, and orange juice until smooth. Transfer to a piping bag and refrigerate until needed.
Roll and Shape the Dough:
- Preheat the oven to 400°F (200°C). Roll out the pastry dough on a lightly floured surface to a thickness of 1/8 inch. Cut into 6-inch circles.
- Lightly moisten the edges of each pastry circle. Pipe a line of citrus cream down the center, then fold the pastry over and seal well, crimping the edges with a fork.
- Place pastries on a lined baking sheet and brush the tops with water. Bake in the preheated oven for 20-25 minutes or until golden brown.
Finishing Touch:
- Allow pastries to cool slightly, then dust with powdered sugar before serving.
Notes
Tammy’s Tips:Â
- For a deeper flavor in the citrus cream, try adding a splash of limoncello to the mixture.
- If ricotta isn't available, mascarpone cheese can be used as a substitute for a richer texture.
- These pastries are best served fresh but can be reheated in a moderate oven for a few minutes before dusting with sugar for a crisp finish.

Frequently asked questions
Can I make these a day ahead and give them as a gift?
Yes — bake them the day before, cool completely, and store in a single layer in an airtight tin at room temperature. They hold their crispness for about 24 hours this way; after that the pastry starts to soften from the filling’s moisture, so same-day or next-day gifting is the sweet spot.
Can I use part-skim ricotta instead of fresh whole-milk ricotta?
You can, but the filling will be noticeably less creamy and may be slightly grainy. If fresh whole-milk ricotta isn’t available, drain part-skim ricotta through a fine mesh strainer for at least 30 minutes before using it to improve the texture.
My dough keeps shrinking back when I roll it out — what’s wrong?
The gluten needs more time to relax. Wrap the dough and return it to the fridge for another 15 minutes, then try rolling again. Trying to force it when it’s springing back just tears the layers.
Can I freeze these before or after baking?
Freeze them before baking, not after. Assemble and seal the pastries, place them on a parchment-lined tray to freeze solid, then transfer to a zip bag. Bake straight from frozen at 400°F, adding about 8 extra minutes to the bake time. Baked and frozen pastries tend to go soggy when thawed.
