Rúgbrauð

Prepare the Batter

Preheat your oven to 300°F (150°C). Grease a loaf pan.

In a large bowl, mix the rye flour, all-purpose flour, baking soda, and salt.

In another bowl, combine the buttermilk, molasses, and brown sugar.

Gradually add the wet ingredients to the dry ingredients, stirring until well combined. The batter should be thick but pourable. If it's too thick, add a little water to reach the desired consistency.

Bake the Rúgbrauð

Pour the batter into the prepared loaf pan.

Cover the pan tightly with aluminum foil to prevent the top from browning too quickly.

Bake in the preheated oven for about 2 to 2.5 hours, or until a toothpick inserted into the center comes out clean.

Cool and Serve

Remove the bread from the oven and let it cool in the pan for about 10 minutes.

Transfer to a wire rack to cool completely.
