Ingredients

For the Dough

  • 350 g wholegrain rye flour
  • 100 g wholegrain wheat flour
  • 50 g wholegrain spelt flour
  • 15 g active rye sourdough starter
  • 320 ml beetroot juice
  • 8–10 g salt
  • 80–100 g walnuts roughly chopped (optional)

Instructions

  • Refresh your sourdough starter until it is active and bubbly (1-2 days before). Mix it with the beetroot juice, then add the wholegrain rye, wheat and spelt flours to form a uniform dough.
  • Cover and let the dough rest for about 30–45 minutes. Add the salt and walnuts (if using), then mix until everything is evenly incorporated.
  • Cover the dough and leave it to ferment at room temperature for about 10–12 hours, or until it has visibly expanded.
  • Shape the dough into a loaf, place it into a well-floured banneton or loaf tin, cover, and let it proof for another 10–12 hours.
  • Preheat the oven to 240°C with a Dutch oven or baking stone. Carefully transfer the dough, score the top, and bake with the lid on (or with steam) for about 20 minutes.
  • Remove the lid (or steam), reduce the temperature to 220°C if needed, and bake for another 30–35 minutes until the crust is deeply browned.
  • Allow the bread to cool completely on a wire rack before slicing. This helps the crumb finish setting and gives the best texture.

Notes

Fresh Starter Matters: A freshly refreshed sourdough starter often produces a lighter loaf, a more open crumb and a milder flavor than an older starter.
Freeze for Later: If you won’t finish the bread within 5–7 days, freeze part of the loaf.
