Gretel always said the best Austrian baking isn't always about flour. Some of the finest Weihnachtsbäckerei, the Christmas cookies that fill every Austrian kitchen from late November onwards, don't use flour at all. Kürbiskernbusserl are proof. They're built on nothing more than egg whites, sugar, and ground Styrian pumpkin seeds, those dark green, almost black kernels that taste like earth and butter and something quietly wild. The meringue does the structural work. The seeds do everything else.

I first tasted these on a trip to Graz with Gretel and my grandmother Eva when I was maybe ten. A woman at the Bauernmarkt had them on a wooden board, sandwiched together with Ribiselmarmelade, red currant jam so tart it made my eyes water. Gretel bought a bag, ate two on the spot, and then spent the rest of the afternoon trying to get the woman to tell her the exact ratio of seeds to sugar. The woman laughed and told her to use her tongue. Gretel respected that.

The texture is what makes people stop mid-bite. The outside shatters into a thin, papery shell. Inside, the ground pumpkin seeds make the center dense and chewy, almost like a soft nougat. That chewiness is the whole point. If you bake them too long and they go crisp all the way through, you've lost what makes them special. Pull them from the oven when the surface is set and dry to the touch but the centers still give slightly when you press them. They firm up as they cool.

The Ribiselmarmelade between the two halves isn't decoration. Its sharp tartness cuts through the sweet meringue and the rich, oily seeds. Without it, the Busserl are pleasant. With it, they're something you can't stop eating.

Kürbiskernbusserl belong to Styria, where pumpkin seed cultivation dates to the 18th century and where Steirisches Kürbiskernöl (Styrian pumpkin seed oil) holds EU Protected Geographical Indication status. The seeds come from a specific hull-less pumpkin variety, the Cucurbita pepo var. styriaca, bred in Styria so the kernels grow without a hard shell. Busserl, meaning 'kisses' in Austrian dialect, describes a whole family of small meringue-based cookies found across Austria's Weihnachtsbäckerei tradition. The Styrian version uses the region's most prized ingredient where other provinces might use hazelnuts or walnuts, turning a simple meringue into a statement of local pride.

  • •Piping bag with 1cm round nozzle (optional)
  • •2 baking trays
  • •Large flexible spatula for folding

Instructions

  1. 1

    Grind the pumpkin seeds

    Spread the 200g of pumpkin seeds on a dry baking tray and toast them in a 150°C oven for about eight minutes, until they smell nutty and have started to pop. Let them cool completely. Toasting deepens the flavor considerably, turning them from pleasant to properly rich. Once cool, pulse them in a food processor until finely ground but still with a little texture. You want something like coarse almond meal, not a paste. If you grind too long, the oil releases and you'll end up with pumpkin seed butter. Pulse in short bursts and check often.

    Look for dark green Styrian pumpkin seeds specifically. They're sold as Steirische Kürbiskerne in Austrian shops and increasingly in good delicatessens elsewhere. Regular pale pumpkin seeds from a health food shop are a different variety entirely and won't give you the same deep, nutty flavor or that beautiful dark green color in the finished cookie.
  2. 2

    Preheat and prepare

    Turn the oven up to 160°C. Line two baking trays with parchment paper. If you have a piping bag and a round nozzle about one centimeter wide, set that up now. If not, two teaspoons work fine. These are farmhouse cookies, not Konditorei showpieces.

  3. 3

    Whip the meringue

    Put the egg whites and the pinch of salt into a spotlessly clean bowl. Beat with an electric mixer on medium speed until they foam and turn white, then increase to high and add the caster sugar one tablespoon at a time. Wait ten seconds between each addition. Rushing the sugar in will collapse the structure you're building. Keep beating until the meringue holds stiff, glossy peaks and feels smooth when you rub a bit between your fingers. If it's grainy, the sugar hasn't dissolved. Keep going.

    Room temperature egg whites whip faster and to a greater volume than cold ones. Separate them thirty minutes before you start. And if even a speck of yolk gets in, start over with a fresh egg. Fat kills meringue.
  4. 4

    Fold in the seeds

    Add the Vanillezucker and lemon zest to the meringue. The lemon zest isn't there for lemon flavor. It's there to brighten the richness of the pumpkin seeds, the way a squeeze of lemon lifts a heavy dish. Now add the ground pumpkin seeds in three additions, folding gently with a large spatula or metal spoon. Cut down through the center, scoop along the bottom, fold over the top. Rotate the bowl a quarter turn and repeat. You want to keep as much air in the meringue as possible while distributing the seeds evenly. The batter will deflate somewhat. That's expected. Just don't stir it like you're making porridge.

  5. 5

    Pipe or spoon the Busserl

    Pipe or spoon rounds about three centimeters across onto the lined trays, leaving two centimeters between each one. They spread slightly but they're not dramatic about it. Press a single whole pumpkin seed gently into the top of each one. This is both decoration and a signal to anyone who picks one up: these are pumpkin seed cookies, and they're proud of it. You should get about 50 individual Busserl from this batch, which will become roughly 25 sandwiched pairs.

  6. 6

    Bake until just set

    Bake for 18 to 20 minutes, until the surface is dry and set and the Busserl have turned a pale golden green. They should feel firm on the outside when you tap them lightly but still give a tiny bit in the center. This is the moment to trust your instincts. If you wait until they feel completely hard, they'll be crisp all the way through when cool and you'll have lost the chewy center that makes these worth making. Pull them five seconds before you think they're done. Let them cool completely on the tray. They set further as they sit.

    Every oven runs differently. Check at 16 minutes the first time you make these. The color change is subtle because the pumpkin seeds are already dark, so rely on touch: dry and firm outside, the slightest give when pressed gently in the center.
  7. 7

    Sandwich with Ribiselmarmelade

    Once the Busserl are completely cool, and I mean completely, not just warm-ish, turn half of them flat-side up. Spoon or pipe about a teaspoon of Ribiselmarmelade onto each one. Red currant jam is traditional and correct here. Its sharp, bright tartness is the counterpoint this cookie needs. Press a second Busserl gently on top, flat side down, until the jam just barely reaches the edges. Let them sit for an hour before serving. The jam needs time to soften the interior slightly and meld the two halves into one coherent bite. Mahlzeit!

Chef Tips

  • •If you can't find Ribiselmarmelade (red currant jam), a good quality sour cherry jam works as a substitute. What you're after is tartness, not sweetness. Apricot jam is too mild here. You need something that pushes back against the richness of the pumpkin seeds.
  • •Store the sandwiched Busserl in a tin between layers of parchment paper. They keep beautifully for two weeks and actually improve after the first day as the jam softens into the meringue and the flavors marry. This makes them ideal for Weihnachtsbäckerei, the Austrian tradition of baking Christmas cookies weeks in advance.
  • •Buy more pumpkin seeds than you think you need. You'll eat a handful while you work. Everyone does. The Styrians know this and account for it.
  • •Don't be tempted to add food coloring. The natural dark green of Styrian pumpkin seeds is beautiful on its own. You'll see it in the batter and in the finished cookie, a muted sage green that looks like nothing else on the Christmas plate.

Advance Preparation

  • •The ground toasted pumpkin seeds can be prepared up to three days ahead and stored in an airtight container at room temperature. Don't refrigerate them; condensation will make them clump.
  • •Un-sandwiched Busserl can be baked up to five days ahead and stored in a tin. Sandwich with jam the day before serving or up to two weeks ahead. They store well either way.
  • •These are classic make-ahead Christmas cookies. In Austria, Weihnachtsbäckerei starts in late November and the tins are filled weeks before Christmas Eve. Kürbiskernbusserl belong in that rotation.
