Steps

Before you start
  • Bring eggs, milk, and butter to room temperature (about 1 hour ahead)
  • Bloom saffron strands in the warm milk to release their color and flavor
  • Line two baking sheets with parchment paper
  • Preheat oven to 400°F (200°C) about 15 minutes before baking
  1. Bloom saffron in milk

    • Place the warm milk (110°F / 43°C) in a small saucepan off the heat.
    • Add the saffron strands and let them steep for 5 minutes, stirring occasionally.
    • The milk will turn a beautiful golden-yellow.
    • Set aside to cool slightly to about 105°F (40°C)—warm but not hot to the touch.
    + Show details

    Ready when: Milk is bright golden-yellow and saffron strands have colored the liquid

    Tip: Don't skip the bloom step—it activates the saffron's flavor and color far better than adding dry strands to dough.

  2. Mix dough base

    • In a large mixing bowl (or stand mixer bowl), combine the saffron-infused milk, instant yeast, granulated sugar, salt, and ground cardamom.
    • Whisk together and let sit for 1 minute until the yeast is moistened.
    • Add the lightly beaten eggs and mix until incorporated.
    • Using a wooden spoon or the stand mixer's dough hook on low speed, gradually add the flour, about 1 cup at a time, mixing until a shaggy dough forms.
    • Do not add butter yet.
    + Show details

    Ready when: Shaggy dough forms and no dry flour remains visible

    Tip: Mixing the yeast with liquid and sugar first—without salt—activates it. Salt inhibits yeast activation, so it's added after the yeast has activated.

  3. Knead and incorporate butter

    • Once the shaggy dough is formed, increase the mixer speed to medium (or knead by hand for about 3 minutes to develop gluten).
    • The dough should become smoother and begin to pull away from the bowl sides.
    • Now gradually add the room-temperature butter cubes, one or two at a time, waiting until each addition is mostly incorporated before adding more.
    • This will take 5–7 minutes.
    • The dough will look slick and slightly glossy when done.
    + Show details

    Ready when: Dough is smooth, elastic, and pulls away from the bowl; no visible butter streaks remain

    Tip: Room-temperature butter incorporates much more easily than cold butter. Cold butter will break the gluten strands and make the dough greasy.

  4. Add raisins and rest dough

    • Gently fold in the raisins with a dough scraper or wooden spoon, turning the dough a few times until the raisins are evenly distributed (about 1 minute).
    • Cover the bowl with a damp kitchen towel or plastic wrap and let the dough rest at room temperature for 10 minutes.
    • This brief rest allows the gluten to relax before the first rise.
    + Show details

    Ready when: Raisins are evenly scattered throughout; dough is smooth and warm

    Tip: Don't overwork the dough when folding in raisins—too much handling after adding butter can toughen it.

  5. First rise

    • Cover the dough bowl with the towel or wrap and place in a warm, draft-free location (around 75°F / 24°C is ideal).
    • Let the dough rise until it has increased in volume by about 50% and shows visible air bubbles on the surface—this will take 45–55 minutes depending on room temperature.
    • The dough should be puffy but not yet doubled.
    + Show details

    Ready when: Dough has risen by about 50% and shows air bubbles and a slight dome

    Tip: Slow, cool rises develop better flavor than hot, fast rises. If your kitchen is cool, place the bowl inside an unheated oven with the light on.

  6. Shape buns

    • Turn the dough out onto a lightly floured work surface (about 2 tbsp flour).
    • Divide the dough into 12 equal pieces (each will be roughly 70–75 grams).
    • Working with one piece at a time, gently shape each into a smooth ball by cupping your hands around the dough and rolling it toward you in short, quick motions, creating surface tension.
    • Place each shaped bun seam-side down on the prepared baking sheets, spacing them about 2 inches (5 cm) apart (you'll have about 6 buns per sheet).
    + Show details

    Ready when: 12 smooth, round buns are shaped and arranged on the baking sheets

    Tip: Don't skip the gentle tension step when shaping—it helps the buns stay round as they rise and bake, preventing flat or misshapen results.

  7. Second riseOven 400°F / 205°C

    • Cover both baking sheets loosely with plastic wrap or a damp kitchen towel (tent it so it doesn't touch the dough).
    • Let the buns rise at room temperature until they are puffy and nearly doubled in size, with buns touching lightly at their sides—this will take 40–50 minutes.
    • Meanwhile, preheat the oven to 400°F (200°C) about 15 minutes before baking is scheduled to begin.
    + Show details

    Ready when: Buns are puffy and lightly spring back when poked gently with a finger

    Tip: Don't let the buns over-rise past the point where they're touching at the sides—they'll merge and won't separate cleanly.

  8. Apply egg wash and pearl sugar

    • Just before baking, gently brush the top of each bun with the egg wash (1 beaten egg mixed with 1 tbsp water), using a pastry brush or the back of a spoon.
    • Work gently so you don't deflate the buns.
    • Immediately sprinkle about 2 teaspoons of pearl sugar onto the top and sides of each bun.
    • The egg wash will help the sugar adhere.
    + Show details

    Ready when: All buns are glazed and generously topped with pearl sugar crystals

    Tip: Apply pearl sugar immediately after egg wash while it's still wet—the sugar will stick much better than if you wait.

  9. Bake bunsOven 400°F / 205°C

    • Place the baking sheets in the preheated 400°F (200°C) oven.
    • Bake for 16–18 minutes, until the buns are a deep golden-brown, especially on the tops, and the pearl sugar has begun to caramelize and sparkle.
    • If the sugar topping starts browning too quickly (after 12 minutes), loosely tent the buns with foil.
    • The buns should sound hollow when tapped on the bottom.
    + Show details

    Ready when: Buns are deep golden-brown; pearl sugar is caramelized and sparkling; bottom sounds hollow when tapped

    Tip: Oven temperatures vary—if your oven runs hot, start checking at 15 minutes to prevent over-browning.

  10. Cool and serve

    • Remove the baking sheets from the oven and let the buns cool on the sheets for 5 minutes.
    • Transfer them to a wire rack to cool for at least 10 more minutes before serving.
    • They are delicious warm, at room temperature, or lightly warmed the next day.
    + Show details

    Ready when: Buns are cool enough to handle safely and the interior is no longer steaming

    Tip: Serving slightly warm (not piping hot) allows the saffron and cardamom flavor to shine without the inside being gluey.

Good to know

Tips
  • Saffron is the star of this bun—it's worth seeking out good-quality strands from a reliable spice vendor. The expense is justified by the unique floral warmth it brings.
  • These buns are traditionally served on St. Lucia Day (December 13th) but are delicious year-round. In Sweden, they're often part of a festive coffee table or breakfast spread.
  • If pearl sugar is unavailable, don't skip the egg wash—the glossy brown buns are beautiful on their own, and a drizzle of white icing or a light dusting of powdered sugar can be applied while still warm.
  • Precision scales are especially helpful for this recipe to ensure consistent bun size and reliable rising times.
Make ahead

The dough can be mixed and allowed to rise once, then refrigerated in a covered bowl for up to 8 hours. Let it come to room temperature (about 30 minutes) before shaping and proceeding with the second rise. Baked buns keep well and can be made 1 day ahead.

Storage & reheating

Store cooled buns in an airtight container at room temperature for up to 2 days. Refrigerate for up to 4 days. Freeze unfrosted buns in a freezer bag for up to 1 month; thaw at room temperature and warm in a 300°F (150°C) oven for 5 minutes. Do not freeze with pearl sugar topping as it will soften; add fresh pearl sugar after warming if desired.

Substitutions
  • ground cardamom → ground ginger or ground cinnamon. Cardamom is traditional but ginger (½ tsp) or cinnamon (¼ tsp) work beautifully if you don't have it on hand. Adjust to taste.
  • raisins (or sultanas), plump and tender → dried currants, dried cranberries, or chopped dried apricots. Other dried fruits add different flavor notes. Use the same weight as raisins.
  • pearl sugar (nib sugar), for topping → Swedish cinnamon sugar (mix 2 tbsp cinnamon with ½ cup sugar), regular coarse sugar, or raw demerara sugar. Pearl sugar's crunch is unique, but other toppings provide sweetness and texture. Pearl sugar is available online and at specialty baking stores.
  • saffron strands → turmeric (¼ tsp) for color, though the flavor profile will differ slightly. Turmeric provides golden color but not saffron's floral notes. If using turmeric, add ½ tsp vanilla extract to the dough for depth.
