Instructions
 

Day 1 – Morning: Prepare Sponge & Scald

Day 1 – Evening: Make the Opara

  • Cover and ferment overnight (10–12 hours). The opara should more than double in volume and smell sweet-sour.

Day 2 – Morning: Final Dough

  • Dissolve honey in warm water.
  • Add all final dough ingredients to mixer bowl. Mix on low (KA2) speed for 6–8 minutes until dough is stiff and cleans the bowl sides.
  • Turn dough onto a dry surface. With wet hands, shape into a 10″ x 4″ loaf.

Baking

  • Smooth the loaf with wet hands and place it in the oven. Immediately raise oven to 445°F (230°C) and bake for 15 minutes.

🌾 A Taste of the Baltic: More Than Just Bread

If bread is the staff of life, Juoda Duona—Lithuania’s traditional dark rye bread—is its sacred heart. This is not just any loaf. It's deep, intense, and packed with heritage, made with time, patience, and the soul of rye.
I’ve long been fascinated by the rye breads of the Russian and Baltic regions. Their complexity, the depth of flavor, the dense crumb—they’re practically edible poetry.
So imagine my delight when I stumbled upon a loaf of imported Latvian rye at a local international grocery store. As I unwrapped it, a sweet-sour, almost floral perfume rose from the dense, mahogany crust. One bite and I was hooked—citrusy, licorice-laced, with a bright, clean finish. I had to recreate it.
But the ingredient list offered few clues—just a simple list: rye flour, wheat flour, malted rye, sour culture, salt, honey, and sugar. It wasn’t until I discovered a Lithuanian food blog that I found a recipe that felt just right—authentic, humble, and utterly captivating.
That’s when I baked this beauty of a bread. And friends, it’s magic.

🍯 What Makes Juoda Duona Special?

  • Rich fermentation process: The sponge, scald, and opara (compound sour) stages develop unmatched depth of flavor.
  • Red rye malt: Adds sweetness, color, and complexity.
  • Sour rye culture: Gives the bread its signature tang and aroma.
  • Traditional baking technique: Slow fermentation, gradual temperature shifts, and a starchy glaze create a loaf that’s authentic and unforgettable.
This is a bread to savor. Slather on a bit of sweet butter, and you’ve got a meal fit for kings—or at least, Baltic grandmothers. 💛
