Add flour, salt, sugar and rosemary in a mixing bowl.
Mix the flour well.
Add yeast and mix.
Add butter and rub it into the flour.
Add mashed potato and mix well.
Add warm water. Bring the dough together using your hand or a spatula.
If you are using a dough kneading machine then allow the dough to be kneaded for at least 10 minutes or till it appears smooth.
If you knead the dough by hand then lightly dust the worktop with a bit of flour.
Knead till you get a soft smooth dough. This may take about 15-20 minutes.
The dough will be sticky or tacky. Don't be tempted to add a lot of flour as that will make the bread dense.
Take the dough out from the dough kneader.
Place it on a lightly floured worktop or board.
Lift one part of the dough and fold it in. Imagine 4 sides of the dough and fold each part over. Check out the video.
Continue doing the quarter fold 2-3 times.
Flatten the dough gently. Add the cheese cubes in the middle.
Fold the dough over it.
Using the sides of your palms, tuck in the sides of the dough to make a smooth round ball.
Grease a mixing bowl with little butter.
Place the dough ball in it. Cover the bowl with a lid or damp towel.Allow it to rise till it is double in size.
As this bread dough has mashed potato, the fermentation time may be less.
Mine got fermented in an hour.
Lightly dust the worktop with some flour.
Take out the risen dough from the bowl.
Flatten it gently. And then again using the sides of your palms, tuck in the dough to make a nice round ball.
Line a baking tray with parchment paper.
Place the dough ball on it. Allow the dough to ferment again till it is double the size.
This may take 30-45 minutes. Cover the dough with a damp towel.
Preheat the oven to 180°C.
Brush the top and sides of the dough with some milk.
Bake the bread for 30-35 minutes till the top is golden brown.
Remove the tray from the oven. Knock the bread. It should sound hollow if it is baked well.
Allow the bread to cool for 5-10 minutes on the tray.
Transfer the bread to a wire rack and allow it to cool further.
Enjoy this soft crumb bread to make sandwiches or toast it.
