01 - In a large mixing bowl, combine bread flour, ground cinnamon, salt, instant yeast, and sugar. Mix thoroughly until evenly distributed.
02 - Add warm water and softened butter to dry ingredients. Stir with wooden spoon or dough hook until shaggy dough forms.
03 - Add raisins and knead by hand or mixer for 7-10 minutes until dough is smooth, elastic, and raisins are evenly distributed.
04 - Shape dough into ball, place in lightly greased bowl, cover with damp towel or plastic wrap. Let rise in warm place for 1-1.5 hours until doubled in size.
05 - Turn dough onto lightly floured surface. Gently shape into round or oval loaf without degassing excessively.
06 - Place loaf on parchment-lined baking sheet or in floured proofing basket. Cover and let rise 45 minutes until puffy.
07 - Preheat oven to 425°F. If using Dutch oven, place it in oven during preheating.
08 - Make shallow slashes on top of loaf with sharp knife or lame to control expansion during baking.
09 - Transfer loaf to hot Dutch oven or baking sheet. Cover with Dutch oven lid or foil tent. Bake 20 minutes.
10 - Remove lid or foil. Continue baking 20 minutes until deep golden brown and hollow-sounding when tapped on bottom.
