01 - In a large mixing bowl, combine bread flour, ground cinnamon, salt, instant yeast, and sugar. Mix until thoroughly incorporated.
02 - Add warm water and softened butter to the dry mixture. Stir with a wooden spoon or dough hook until a shaggy, sticky dough forms.
03 - Add raisins and knead by hand or stand mixer for 7–10 minutes until smooth, elastic, and raisins are evenly distributed throughout.
04 - Shape dough into a ball and place in a 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 degas and shape into a round or oval loaf, creating surface tension.
06 - Place loaf on parchment-lined baking sheet or floured proofing basket. Cover and let rise for 45 minutes until puffy.
07 - Preheat oven to 425°F. If using Dutch oven, place it in oven during preheating to get hot.
08 - Using a sharp knife or lame, make 3–4 shallow diagonal slashes across top of loaf to control expansion during baking.
09 - Transfer loaf with parchment into hot Dutch oven or onto baking sheet. Cover with lid or tent loosely with foil. Bake for 20 minutes.
10 - Remove lid or foil. Continue baking for 20 minutes until deep golden brown and loaf sounds hollow when tapped on bottom.
11 - Remove from oven. Optionally brush top with melted butter for softer crust. Cool on wire rack for at least 1 hour before slicing.
