Authentic St Martins Croissants Recipe

A detailed st martins croissants recipe allows home bakers to recreate rogal swietomarcinski, the prized pastry of Poznan. Shaped like a horseshoe and filled with a luxurious paste of white poppy seeds, ground nuts, raisins, and almond essence, this pastry celebrates Saint Martin's Day on November eleventh but remains beloved year-round across Poland.

Making authentic croissants requires laminating a yeast-raised dough with butter through repeated folds, creating alternating flaky layers that cradle the rich, aromatic filling.

Ingredients for Dough, Filling, and Glaze

Because this regional pastry features complex layers and dense filling, gather your ingredients before beginning:

For the Laminated Dough

Bread flour: Five hundred grams of high-protein wheat flour.
Milk: Two hundred milliliters of whole milk, lukewarm.
Yeast: Thirty grams of fresh yeast or eight grams of active dry yeast.
Butter: Two hundred and fifty grams of cold unsalted butter with eighty-two percent fat content, reserved for rolling.
Sugar and egg: Sixty grams of sugar, one large egg, and one egg yolk.
Salt: Half a teaspoon of fine salt.

For the White Poppy Seed Filling

White poppy seeds: Three hundred grams. White seeds are milder and sweeter than traditional blue poppy seeds.
Nuts: One hundred grams of blanched almonds and one hundred grams of walnuts, finely ground.
Sponge cake crumbs: One hundred grams of finely crushed plain sponge or ladyfingers to bind moisture.
Aromatics and sweets: Eighty grams of sugar, two tablespoons of honey, fifty grams of finely chopped candied orange peel, and pure almond extract.

If you enjoy classic Polish festive baking like a rolled poppy seed roll or a light, fluffy yeast cake, mastering this laminated version will expand your baking skills.

Making the White Poppy Seed Filling

Place the white poppy seeds in a saucepan, cover with boiling water or milk, and simmer gently for twenty minutes. Drain thoroughly through a fine-mesh sieve lined with cheesecloth to remove all excess liquid.
Grind the drained poppy seeds twice through the fine plate of a food grinder.
In a wide pan, melt two tablespoons of butter with honey and sugar. Add the ground poppy seeds, ground nuts, and candied orange peel. Cook over low heat for five to seven minutes, stirring constantly until thick.
Remove the mixture from the heat, stir in the cake crumbs and almond extract, and let the filling cool completely before assembling.

| Step | Technique | Goal | | --- | --- | --- | | Scalding Seeds | Simmer in water or milk | Softens seed coats and removes bitterness | | Double Grinding | Fine meat grinder plate | Releases natural oils for a creamy paste | | Crumb Addition | Sponge cake crumbs | Binds moisture so filling stays inside dough |

Laminating and Shaping the Pastry

Laminating yeast dough demands patience and keeping your workspace cool.

Dissolve the yeast in warm milk with one tablespoon of sugar. In a large bowl, combine flour, remaining sugar, salt, egg, yolk, and the yeast mixture. Knead until smooth and elastic. Flatten into a rectangle, wrap in plastic, and chill for forty-five minutes.
Pound the cold butter between two sheets of parchment paper into a smooth rectangle about two-thirds the size of your dough slab.
Roll the chilled dough out onto a lightly floured surface. Place the butter block in the center, fold the dough flaps over to enclose it completely, and pinch the edges.
Roll the parcel into a long rectangle, then fold it in thirds like a letter (single turn). Wrap and chill for thirty minutes. Repeat this rolling and folding process two more times, chilling between each fold.
Roll the finished laminated dough to a thickness of four millimeters. Cut out tall triangles with bases roughly ten to twelve centimeters wide.
Place a generous log of white poppy seed filling across the wide base of each triangle. Roll the dough up toward the tip, gently pulling the tip to create tension. Bend the ends inward to form a horseshoe shape.
Place the shaped croissants on parchment-lined baking sheets, cover loosely with a kitchen towel, and let rise for thirty minutes until puffy.
Bake at 180 degrees Celsius (350 degrees Fahrenheit) for twenty to twenty-two minutes until deeply golden brown.

Finishing Glaze and Toppings

While the croissants bake, prepare a simple sugar glaze by whisking one cup of powdered sugar with two tablespoons of warm water or orange juice. Brush the warm pastries generously with glaze immediately after removing them from the oven. Scatter chopped roasted peanuts or blanched almonds over the wet glaze so they adhere firmly.

Frequently Asked Questions

Can I substitute blue poppy seeds for white poppy seeds?

While blue poppy seeds work mechanically, they carry a more earthy, assertive flavor and darken the pastry interior. White poppy seeds offer a delicate, nutty flavor that is traditional for this specific Poznan pastry.

How do I prevent the filling from leaking out?

Always cool the filling completely before placing it onto the raw dough. Sponge cake crumbs absorb excess moisture during baking, and firmly pinching the starting roll locks the filling inside the laminated layers.

How long do St Martin croissants stay fresh?

Because of the rich butter content and sugar glaze, these croissants remain moist and tender for up to three days at room temperature when kept in a closed bakery box or under a cake dome.
