Kormos
Greek Chocolate Log with Toasted Hazelnuts, Coffee, Brandy & Orange
Dark chocolate poured over broken butter biscuits and toasted hazelnuts, rolled into a log, chilled hard, and sliced into mosaic rounds. Every Greek household has a version; this one is salted properly and cut with orange, which is most of the difference between good and forgettable.
US cups, tbsp and tsp are approximate. Spoon and level flour. Some ingredients use oz/lb when spoon measures would be unreliable.
Kormos means tree trunk, and in Greece it is the dessert made from what the cupboard already holds: a package of petit-beurre biscuits, a bar of chocolate, whatever brandy is on the shelf. Mothers make it with kids because there is no oven and no way to fail visibly, then it comes out of the fridge after dinner sliced thin, and the adults eat more of it than the kids do. It travels under other names too, mosaiko in Greece for the mosaic face of the slice, salame di cioccolato across the water in Italy. The honesty of it is the charm: six ingredients, one bowl, and a log that looks like it fell off a tree until you cut it open.

The Tools
- Kitchen scale · The chocolate-to-fat-to-biscuit ratio is what sets the log; weigh it
- Sheet pan (toast the hazelnuts)
- Clean kitchen towel (rub the skins off)
- Large mixing bowl
- Heatproof bowl (melt the chocolate)
- Small saucepan (double-boiler base)
- Whisk
- Rubber spatula
- Microplane (orange zest)

✚ ends up in the sink · essentials unless marked optional
The Log
Why this works Chocolate and butter firm in the refrigerator while a little olive oil keeps the slice tender. Broken dry biscuits and toasted hazelnuts provide the mosaic and crunch; warm emulsion clings better once cooled to a slow ribbon. Coffee adds bitterness and orange zest supplies aroma, not acid. Taste the complete mixture with a biscuit piece before shaping so salt and sweetness are judged at the actual ratio.
- 80g (2/3 cup), whole Hazelnuts 80 g · Skin-on is fine; the toast loosens the skins
- 200g Dairy-free petit-beurre-style tea biscuits 200 g · The hard, dry, stamped kind; soft cookies dissolve into the chocolate and the mosaic disappears. Several major petit-beurre brands are dairy-free, read the label
- 200g, chopped Dark chocolate (60-70%), dairy-free 200 g · Bar chocolate, not chips; the log is mostly this, so buy it deliberately
- 90g Unsalted butter 90 g · Use unsalted butter, 82% fat for laminated pastry. Follow the step for cold, softened or melted butter.
- 30g (2 tbsp) Extra virgin olive oil 30 g · A peppery one. It keeps the cold slice tender and adds a low fruit note under the chocolate
- 45g (6 tbsp), plus about 2 tbsp for casing the log Powdered sugar 45 g · Dissolves clean in the warm base; the extra is the salami-casing dust at the end
- 3 tbsp (45g), cooled Strong coffee or espresso 45 g · Bitterness against all that richness; you taste depth, not coffee
- 2 tbsp (30g) Brandy (or Metaxa) 30 g · The Greek pantry pour
- 1 tsp Vanilla extract
- 2 tsp, fine (about 1 orange) Orange zest · Finely grated orange zest provides aroma, not meaningful acidity; avoid the bitter white pith.
- 1/4 tsp, plus flaky salt for serving Fine sea salt · In the base and on the slice both; cold mutes seasoning

Toast the hazelnuts 4 min hands-on · 10 min wait
Oven to 350°F (175°C). Toast the hazelnuts on the sheet pan 8-10 minutes, shaking once. Bundle them hot into the towel, rest 2 minutes, and rub hard to shed the skins. Crack them coarse with the flat of a knife: halves and big pieces, not dust.
Look for Skins flaking off to show deep gold underneath, and the smell fills the kitchen. Cracked, the pieces are the size of split peas and bigger.
Take care Hazelnuts go from toasted to burnt in the last minute and taste acrid past gold. Pull them when the skins split and your nose says so, not later. -
Break the biscuits 4 min hands-on
Break the biscuits by hand into rough shards, 1/2 to 3/4 inch, straight into the large bowl. Some smaller flecks and dust are inevitable and fine; they thicken the matrix.
Look for A bowl of jagged, irregular shards, the pieces still recognizable as biscuit.
Take care The bag-and-rolling-pin move makes crumbs, and crumbs make a brown log with no mosaic. Hands only. The broken faces ARE the finished slice. -
Melt the base 4 min hands-on
Set the heatproof bowl over an inch of barely simmering water, bowl not touching the water, and melt the chocolate and butter together, stirring, until smooth.
Look for Fully liquid, glossy, no lumps.
Take care Use gentle heat and stir. If the emulsion separates after the coffee is added, a teaspoon of warm coffee and steady stirring can help it smooth again. -
Season the base 3 min hands-on
Off heat, whisk in oil, powdered sugar, coffee, brandy, vanilla and fine salt until glossy. Cool a spoonful, coat a small biscuit piece and taste the actual combination: dark chocolate first, coffee behind it and a clean salt finish. Add salt only a pinch at a time.
Look for Glossy, loose, and completely smooth, with no oil slick riding the surface.
Take care Coffee is a deliberate liquid in the emulsion. Add it while the base is warm and stir smooth before cooling. -
Cool to a ribbon 1 min hands-on · 12 min wait
Let the base sit at room temperature 10-15 minutes, stirring twice, until it thickens enough to fall from the spatula in a slow, folding ribbon.
Look for A ribbon that sits on the surface a second before sinking. Warmer than that, it is paint; colder, it is spackle.
Take care Fold at pouring-hot and the coating slides off the shards and pools at the bottom of the log: fudge on one face, loose rubble on the other. The ribbon is the go signal. -
Fold the mosaic 3 min hands-on
Add the hazelnuts and orange zest to the biscuit shards, pour the base over, and fold with the spatula until every shard is coated and the mixture mounds on itself.
Look for A thick, glossy rubble that holds together when pressed against the side of the bowl, no dry biscuit faces showing.
Take care Fold, don't stir; aggressive mixing grinds the shards smaller with every turn and the mosaic coarseness is the point. -
Roll the log 5 min hands-on
Scrape the mixture onto a large sheet of parchment in a rough 12-inch line. Using the paper, roll and press it into a compact log about 2 1/2 inches across, then roll the parchment around it and twist the ends tight like a candy wrapper. Rap the wrapped log against the counter a few times, rotating, to knock out air pockets.
Look for A firm, even cylinder with no visible hollows at the exposed ends, ends twisted tight.
Take care Air pockets become holes in the sliced mosaic. The rap-and-rotate is what closes them; skip it and the third slice in has a crater. -
Chill hard 1 min hands-on · 4 h wait
Refrigerate wrapped for at least 4 hours. Use within four days or freeze, well wrapped, for up to a month.
Look for Firm as cold butter along its whole length; pressing leaves no dent.
Take care Sliced early, it smears instead of cutting and the mosaic drags. The cold IS the oven here; give it the full time. -
Case and slice 4 min hands-on
Unwrap, and roll the log in the reserved powdered sugar to coat, the salami-casing look. Slice into 3/4-inch rounds, sixteen from the log with the sharp knife, wiping the blade between cuts.
Look for Each round a clean mosaic: pale biscuit shards and gold hazelnut set in near-black chocolate, the white-dusted rim holding it like a frame.
Take care A dirty blade drags chocolate across the pale shards and muddies the face. Wipe every cut; the mosaic is the whole reveal.
When it goes wrong
| Problem | Cause | Fix |
|---|---|---|
| Slices crumble apart instead of holding a round | Biscuits broken too small, or the base folded too cold to bind them | Bigger shards and a base at the slow-ribbon stage; re-roll the crumbles tight in parchment and chill again, the log forgives |
| Log never set firm enough to slice | Fat out of ratio: too much oil or too little chocolate, or a warm fridge spot | An hour in the freezer rescues tonight; next time weigh the chocolate, butter, and oil rather than eyeballing |
| White streaks on the surface after a few days | Fat bloom from temperature swings in the fridge | Cosmetic only, flavor untouched; the powdered-sugar casing hides it, so re-dust and slice |
To the Table
Slice to order, straight from the fridge; the rounds are at their best cold and firm.
Overlap the rounds along a narrow board like a cut salami, mosaic faces up, and let the joke land before anyone tastes it.
A single flake of Maldon on each round just before serving; cold mutes salt, and this is where the seasoning finishes.
Strong coffee alongside, Greek or otherwise. In Greece this is the after-dinner slice that keeps the table talking another hour.
Keep the uncut log wrapped in the refrigerator and use within four days, or freeze a portion. Slice only what the table will eat.

Words We Used
- Kormos
- Greek for tree trunk: a no-bake log of chocolate and broken biscuits, sliced into rounds. Also called mosaiko for the mosaic face of the slice; Italy makes its cousin as salame di cioccolato.
- Petit-beurre
- The hard, dry, stamped French tea biscuit that Greek households build kormos on. Its dryness is structural: a soft cookie dissolves into the chocolate and the mosaic vanishes.
- Fat bloom
- The dull white streaks chocolate develops when temperature swings push cocoa butter to the surface. Cosmetic, not spoilage; flavor is untouched.
- Set-fat dessert
- A dessert that firms in the cold instead of the oven: melted chocolate and butter recrystallize into a sliceable matrix. The fridge is the oven, and chilling time is the bake time.
