A Finnish rye sourdough shaped here as two flat ring loaves, made from rye flour, water, salt and an established rye leaven.

Rye bread and Finnish identity

Rye bread won a national-food vote held for Finland's 2017 independence centenary. ThisisFINLAND reports that almost 40,000 people voted in autumn 2016, with nearly 10,000 choosing rye bread. That dated event documents its modern cultural standing; it does not establish when rye bread or this recipe first appeared.

The same article describes bakers preserving a portion of sourdough as a root for later batches. This continuing practice links successive bakes, but the age or family history of a starter does not prove its safety. The source method's bubbling and aroma cues remain readiness observations rather than microbiological tests.

The ring-loaf form

Ruisleipä includes more than one loaf shape. ThisisFINLAND distinguishes eastern Finland's round limppu from the flatter western reikäleipä, traditionally threaded onto poles suspended below the ceiling. The two flat loaves with central holes in this recipe follow that ring form.

The pole-storage account is historical context, not a tested storage instruction for this household bake. This page keeps the Martha Association's republished quantities and fermentation schedule without assigning a birthplace, a first attestation or a finished-bread shelf life.

History

Rye bread is a longstanding Finnish staple. Eastern Finland is associated with round limppu, while western Finland is associated with flat reikäleipä; this version uses the ring-loaf form. No first attestation for this specific formula is established here.

Method

Risks and precautions · Standard risk

Use a clean jar and utensils for starter preparation. The cited recipe does not give a defined starter temperature or microbiological endpoint; aroma and bubbling are source cues for readiness, not safety tests.

  1. If you do not have an established rye starter, mix 3 tablespoons rye flour with 3 tablespoons lukewarm water in a small glass jar. Cover loosely and leave in a warm place for two days.
  2. On day three, stir in 2 tablespoons each of rye flour and lukewarm water. Cover loosely and leave in the same place for one more day. The young starter is ready for use on day four; its flavour strengthens with repeated use.
  3. For the first sourdough phase, mix 2 dl lukewarm water, about 1 dl starter and 2 dl rye flour to a smooth paste. Cover loosely and leave warm overnight, or until bubbling properly with a mild sour aroma.
  4. Add 6 dl lukewarm water and 1/2–1 tablespoon salt to the sourdough and stir until the salt dissolves. Mix in 1.6–1.8 litres rye flour a little at a time; flour absorption varies. Knead vigorously by hand for at least 10 minutes or mechanically for 5 minutes, until smooth and quite firm.
  5. Cover the dough with a cloth and leave it in a warm place until doubled, about 3–6 hours depending on temperature. Save a portion of dough in the bowl as starter for the next bake.
  6. Turn the dough onto a well-floured surface and knead it vigorously several times. Divide into two pieces and shape each as a flat round loaf with a central hole. Set them on a baking sheet, cover with a cloth and proof for 2–3 hours, depending on warmth. A light finger press should spring back quickly. Prick the surface with a fork.
  7. Bake the ring loaves at 225 °C for 20–30 minutes. Cool the bread under a thick cloth.
