Prepare 153g of potato for dough by boiling and crushing it when it is hot.

Place 55g of strong flour, yeast, salt, sugar, milk and water in a mixing bowl and operate at low speed to form a lump.
The amount of water varies depending on the potato in it, so please add water little by little based on the dough condition.
If you put in too much, the dough will get tough, so make sure to add a little bit of the dough.

When you add water and turn it, the dough should be slightly sticky.
If it's thick, the bread doesn't taste good. The dough needs to be a little hard to make the bread soft.

When the dough starts to fall off the wall, lower the speed by one step and add oil
Use extra Virgin Olive Oil
If you put a lot in at once, the dough can separate and take a long time to separate, so it can ruin the dough
Divide several times and add oil to the batter until oil is mixed

It keeps working at medium speed, but when the dough falls off the wall of the dough and the dough becomes smooth, you can imagine that the dough is complete

When the dough is complete, sprinkle the mat with the powder, apply a little powder on your hands, and make the dough into a lump.
Put it in a bowl and perform the first fermentation. I put hot water in the microwave to adjust the temperature and humidity
It's been fermented for about 40 minutes.The temperature is 27 and the humidity is 70%.

Please test if the dough is done well. Put powder on your fingers and poke the dough so that the hole doesn't get wrinkled, you can proceed to the next step
Fold the dough and take out the gas
Weigh the dough on the scale.Please divide it into 7 pieces.

Round and let the dough rest for 10 to 15 minutes.Always cover the dough with plastic so it doesn't dry

In the meantime, prepare the filling ingredients. Cut the potatoes into cubes and also the Colby Jack cheese.
Please measure and prepare roll cheese, too.

Press the dough with your hands to spread it out
Flatten the dough roundly and allow the smooth part to go down.
Place colby jack cheese at the bottom and stack roll cheese and potato slices.

Cover the filling like a steamed bun
Flip it over and trim the shape nicely.
Place dough in mold and press flat.

After plastic surgery, mix olive oil and parsley and spread evenly over the dough.
Let's do the second fermentation for 30 minutes
I ferment until it rises a little above the 8.5 x 3 cm frame.

Apply a little more oil
Cut the middle of the dough into a cross shape.

Place remaining potatoes and Colby Jack cheese on top

Bake in a 200 degree oven for about 20 minutes.
