Cultural Significance

Recently voted as Finland's national food, Ruisleipä is universally loved. Unlike German or Russian rye breads which often contain wheat or molasses, Finnish rye bread is typically 100% rye, giving it a robust, sour flavor and incredibly dense texture.

Ingredients

  • 1 cup (200g) active rye sourdough starter (juuri)
  • 3 cups (700ml) lukewarm water
  • 1 tbsp salt
  • 6-7 cups (750g - 850g) whole grain rye flour

Step-by-Step Instructions

  1. Create the Sponge (Day 1): In a large bowl, mix the active starter with the lukewarm water and 3 cups of the rye flour. Cover with a cloth and let it ferment at room temperature for 12-24 hours until it's bubbly and smells pleasantly sour.
  2. Make the Dough (Day 2): Add the salt and gradually mix in the remaining rye flour. Knead the dough vigorously with your hands or a strong mixer until it becomes a stiff, slightly sticky paste.
  3. First Rise: Cover the bowl and let the dough rise in a warm place for about 2-3 hours, or until it has noticeably expanded.
  4. Shape: Turn the dough onto a rye-floured surface. Divide it in half and shape into round, flat disks (about 1 inch thick). Use a glass to cut a hole in the center of each disk (the traditional reikäleipä shape).
  5. Second Rise: Place the shaped loaves on parchment paper, cover, and let them rise for another hour. Prick the surface all over with a fork before baking.
  6. Bake: Bake in a preheated oven at 430°F (220°C) for 30-40 minutes until the crust is hard and dark. Wrap the hot bread in a thick kitchen towel while it cools to soften the crust slightly.
