The Menhir Sarrasin - A Breton Buckwheat loaf

Russet red-brown buckwheat loaf made distinctive by the addition of roast buckwheat flour. Bake a dozen and you could build your own Stonehenge. Or Breadhenge. The menhir (standing stone) shape is easily made before the final proof. I love it when your own take on a bread is the latest addition to a chain that extends back into the mists of time. In this case, I was inspired by the Farine blog (http://www.farine-mc.com/2015/05/meet-baker-eric-marche.html) article about Breton-based baker Éric Marché. In the blogpost MC writes about how M.Marché roasts a small percentage of the buckwheat flour in his menhir-shaped loaves. I’ve never been a huge fan of buckwheat bread, but this sounded worth a try. It was. It’s a great idea. Delicious. This is my version of Éric Marché's loaf, using, as a template, Dan Leader’s Buckwheat Bâtard recipe which, apparently, he adapted, in turn, from an Éric Kayser recipe. Anyway, I hope I've done them justice. Alternatively, substitute half the strong bread flour for wholemeal and you'll get a darker loaf more akin to M.Marché's original. Great with cheese or cured meats.

Makes 2 x 440g loaves (baked, approx).



  • 40g liquid (100% hydration) sourdough starter
  • 45g water
  • 70g buckwheat flour



Roast the buckwheat:

  1. Roast the buckwheat in a 160/140(fan)℃ (320/280°F) oven for a total of 15 minutes (mixing it every 5 minutes to prevent it from burning.
  2. Set aside to cool to room temperature. You can store it like any other flour.

To form the buckwheat levain:

  1. Mix the ingredients well, cover and let stand for 8-12 hours or overnight.
  2. It makes a medium-stiff levain. Don't expect a huge amount of activity with buckwheat flour, but you should expect to see a moderate increase in volume.

Form the dough:

  1. Combine the buckwheat levain with the water. Break up the levain so it can be easily mixed with the rest of the ingredients.
  2. Add the bread/wholemeal flour, buckwheat, and roast buckwheat. Mix well.
  3. Autolyse for 30 minutes.
  4. Add the salt. and mix.
  5. Knead until the dough passes the windowpane test - about 5 minutes with a stand mixer (or 8-10 minutes by hand). You will have a smooth, creamy dough that still tears if you pull at it.
  6. Leave it in its bowl, cover, then bulk ferment the dough for 1 hour.
  7. Stretch-and-fold in the bowl, rotating one quarter between folds for one complete turn of the bowl.
  8. Do the windowpane test. It you feel the gluten is still under-developed, do another stretch-and-fold.
  9. Cold retard for 6-10 hours (or overnight).
  10. Then gently de-gas, divide the dough, and pre-shape into boules or blunts. No need to be fancy: do it in four quick turns per boule - you don't want to rip the skin.
  11. Rest for 20 minutes.
  12. Shape into menhirs. To do this gently de-gas each boule/blunt again. Next flatten and stretch them into the form you'd use to shape a bâtard, but with one side being shorter than the other. Now stretch and fold under tension - again, just as you'd do with a bâtard - but don't seal the final fold with the heel of your hand, leave it as it is. You should now have two loaves, each in the shape of a blunt-nosed cone (see photo below).
  13. Set aside, make sure the seam is on the side of each loaf, cover, and prove for 1-2 hours.
  14. Preheat your oven to 230/210(fan)℃ (450/410°F). Prepare your steam tray too.
  15. When the loaves are ready, spray their upper surfaces with water then sprinkle with seeds.
  16. Score to enhance the shape by running your lame along the seam on the side from tip to base.
  17. Steam the oven. I just pour water onto my steam tray which has been sitting in the oven for ten minutes. A few squirts of water onto your baking stone can also be a big help.
  18. Bake - immediately turning the heat down to 220/200(fan)℃ (430/400°F) - for 25-30 minutes.
  19. Remove the steam tray 15 minutes into the bake.
  20. Once the loaf turns a golden russet brown and the base is hollow to the tap, remove from the oven and set aside to cool.


Menhirs are ancient standing stones, sometimes six or seven thousand years old. Thousands of them are found in Britain (Stonehenge), Ireland, and northern France. In particular, they dot the landscape of Brittany (the forest of them at Carnac has to be seen to be believed), hence Éric’s inspiration.

And, as those of you who read Asterix and Obelix books as a kid will know, a menhir is also the giant rock Obelix uses habitually as a weapon to flatten Roman legionaries. I was a childhood fan (still am), so I just couldn’t resist.
