Dissolve yeast in warm water in a bowl.

Add sugar, egg, softened butter, salt, cardamom, and 2 cups of flour to the yeast mixture.

Mix well to combine.

Stir in raisins, citron, and enough remaining flour to form a soft dough.

Turn the dough onto a floured surface.

Knead the dough until smooth and elastic, about 6-8 minutes.

Place the dough in a greased bowl, turning once to grease the top.

Cover the bowl and let it rise in a warm place until doubled, about 1 hour.

Punch the dough down.

Divide the dough in half.

Shape each portion into a flattened ball.

Place each ball in a greased 9-inch round baking pan.

Cover the pans and let the dough rise in a warm place until doubled, about 1 hour.

Bake at 350°F (175°C) for 30-35 minutes, or until golden brown.

Remove the bread from the pans and let it cool on wire racks.
