How to Make Puff Pastry Tarts with Egg Salad and Sprats

Remove the puff pastry from the freezer 30 minutes before cooking. Dust your work surface with a thin layer of flour, place the dough on it, and let it rest at room temperature. Roll the dough out to a thickness of 3 millimeters (1/8 inch) and cut it into 12×12 cm (4.5×4.5 inch) squares.

Fold each square in half diagonally to form a triangle.

Fold each square in half diagonally to form a neat triangle.

Step in 1 centimeter (about 3/8 inch) from the edge and make a clean cut along one short side of the triangle, stopping about 1.5 centimeters (about 5/8 inch) before the top angle. Repeat this on the opposite side. Do this for all the pastry triangles.

Make clean cuts along the edges, leaving the top corner intact to form the future borders of the tart.

Unfold the dough squares. Lift the cut borders and fold them over each other crosswise, as shown in the picture, to create a raised edge.

Unfold the dough and fold the cut edges over each other crosswise, creating a hollow center.

Crack one egg into a small bowl and whisk it with a fork until smooth. Brush the pastry shapes with the beaten egg, making sure to brush underneath the folded strips so they stick together and do not lose their shape during baking.

Carefully brush the pastry surface with beaten egg to achieve a beautiful glossy shine after baking.

Transfer the prepared pastries onto a baking sheet lined with parchment paper.

Preheat your oven to 200 degrees Celsius (400 °F). Bake the pastries in the preheated oven for 15 to 20 minutes until they turn a deep golden brown.

Use a sharp knife to carefully cut out the centers of the baked pastries. This creates perfectly hollow little tart shells ready for the egg salad.

Carefully cut out the centers of the pastries to make room for the egg salad.

Prepare the egg salad. Hard-boil two eggs, cool them down, and peel them. Grate the processed cheese (a soft, mild spreadable cheese block popular in Eastern Europe) and the hard-boiled eggs on a coarse grater.

For the filling, coarsely grate the hard-boiled eggs and slightly chilled processed cheese.

Dress the grated eggs and cheese with mayonnaise, then season with salt and pepper to taste. If you are a fan of garlic, I highly recommend adding one grated clove at this stage.

Stir in the mayonnaise, and add salt and pepper to taste. You can also mix in some minced garlic at this stage.

Mix everything thoroughly, and your egg salad is ready. Here is a little chef’s secret: if your egg yolks are a bit pale, fold in 1/4 teaspoon of ground turmeric for a vibrant and appetizing color!

Fill the hollowed puff pastry tarts generously to the brim with the egg salad.

Drain the sprats (small smoked Baltic fish in oil) on a paper towel to remove excess oil. Top each tart with three little fish. Slice the pickled red bell pepper into thin strips. Garnish the tarts with the pepper strips and a fresh herb leaf, then serve immediately. Bon appétit!

If you plan to serve these puff pastry tarts with egg salad and sprats at a dinner party, use a clever professional chef's trick: bake the pastry shells and make the egg filling in advance, but only assemble them right before your guests arrive. This keeps the dough incredibly crisp and prevents it from getting soggy from the dressing. You can store the baked shells in an airtight container at room temperature and keep the salad in the fridge, saving you a ton of time on the day of your event. For a fun flavor twist, experiment with your garnishes. Instead of pickled peppers, try thin slices of fresh cucumber or capers to add a bright, acidic pop. If you want to give the appetizer a bit more of a kick, fold some finely chopped dill or a dab of whole-grain mustard into the egg mixture. Serve these beautiful bites on a large, flat platter lined with lettuce leaves to highlight their festive appeal and give them a truly restaurant-quality presentation.
