01 - In a large mixing bowl, combine bread flour, ground cinnamon, salt, instant yeast, and sugar. Mix thoroughly to distribute evenly.
02 - Pour in warm water and add softened butter. Stir with a wooden spoon 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 a damp towel or plastic wrap. Let rise in a warm place for 1–1.5 hours until doubled in size.
05 - Turn dough onto a lightly floured surface. Gently degas and shape into a round or oval loaf, creating surface tension.
06 - Place loaf on a parchment-lined baking sheet or in a floured proofing basket. Cover and let rise for 45 minutes until puffy.
07 - Preheat oven to 425°F. If using a Dutch oven, place it inside during preheating to get thoroughly hot.
08 - Using a sharp knife or lame, make 3–4 shallow slashes across the top of the loaf to allow for controlled expansion.
09 - Transfer loaf with parchment into the preheated Dutch oven or onto baking sheet. Cover with lid or tent loosely with foil. Bake for 20 minutes.
10 - Remove lid or foil and continue baking for 20 minutes until deep golden brown and loaf sounds hollow when tapped on the bottom.
11 - Remove from oven and brush with melted butter if desired. Transfer to a wire rack and cool for at least 1 hour before slicing to set the crumb.
