Walnut Tartlets (Kosárka)

The secret to a perfect tartlet lies in the fat content: butter coats the flour particles, preventing excessive gluten development, resulting in a short, crumbly pastry rather than a chewy one. These mini pies are a staple at Hungarian weddings and holidays, where the toasted walnut filling caramelizes, harmonizing with the neutral buttery crust.

Instructions

1

Sift the flour into a bowl, mix in salt and half the powdered sugar (1/3 cup). Rub the cold butter cubes into the flour quickly until it resembles damp sand.

Tip: Work fast or use a food processor! If the butter melts, the dough will be tough.
2

Add the egg yolk and lemon zest, then knead just until it comes together into a ball. Wrap in plastic and chill for at least 30 minutes.

Tip: Chilling allows the butter to resolidify, essential for a flaky texture.
3

While the dough rests, make the filling: mix ground walnuts with the remaining powdered sugar, vanilla, apricot jam, and enough milk to make a thick but spreadable paste.

Tip: The acidity of the jam balances the richness of the walnuts.
4

Preheat oven to 350°F (180°C). Lightly butter the metal tart molds.

Tip: Metal molds brown the crust better than silicone.
5

Roll out the cold dough to 1/8 inch thickness on a floured surface. Cut circles slightly larger than your molds and press them in evenly.

Tip: Use your finger to press the dough into the fluted edges.
6

Fill the tart shells with the walnut mixture (don't overfill, they puff up). Place in the hot oven.

Tip: Top with a walnut half for a crunchy garnish.
7

Bake for 15-20 minutes until the pastry edges turn golden brown.

Tip: The scent of toasted nuts tells you it's almost done.
8

Cool in molds for a few minutes, then carefully turn them out while still warm. Dust with powdered sugar before serving.

Tip: Warm pastry is fragile, but if fully cooled, the sugar might stick to the mold.

Recipe FAQ

Why did the dough stick to the mold?
Likely insufficient greasing, or the dough was too warm when pressed in. Use cold butter and flour the molds!
Why is the crust hard?
You overkneaded it. If the butter melts from hand warmth and flour meets water, the dough becomes elastic (rubbery) instead of crumbly.
Can I use other fillings?
Absolutely! Poppy seed, chestnut, or sweetened ricotta fillings are excellent, though walnut is the classic choice.
