1. First prepare all the ingredients.
2. All dough ingredients except butter and salt are put into the noodle bucket of the chef's machine.
3. Start the cook machine, mix the ingredients at low speed, and then increase the speed a little bit to beat the dough to a coarse film state.
4. Add butter and salt that have been softened at room temperature, and continue to beat until a firmer transparent film can be pulled out.
5. Gather smoothly into the fermentation box, ferment to 1.5 times the size.
6. Next, prepare the purple potato filling, peel and steam the purple potato.
7. Put the steamed purple sweet potato, condensed milk, and butter into a compact bag, and use a rolling pin to beat them into a puree.
8. After the fermentation is over, divide it into 2 equal parts. Exhaust the air again to gather and relax for 15 minutes, then take out one piece and roll it into a rectangle.
9. Spread the prepared purple potato filling.
10. Fold down on the upper third, then fold down to form a small rectangle, and relax again for 10 minutes.
11. Gently roll out a little bit with a rolling dough, leave a little space on the upper end and cut into long strips evenly with a knife.
12. Rotate each one in one direction in turn and twist it into a spiral.
13. Roll it up from the end without cuts, close it down, put it into the toast box, cover the lid and put it in the oven at 38 degrees, let it rest and ferment for 30-40 minutes.
14. Then put it into the lower layer of the preheated oven and bake at 165 degrees for about 35 minutes. (The specific time and temperature need to be adjusted according to the temper of the oven)
Tips:1. Different brands of flour have different water absorption. The liquid is adjusted according to the state of the dough. It is better to pre-hot liquid when making it for the first time.
2. Be gentle when rolling the dough. If the dough has a high humidity, you can mix it with a little hand powder. A little can not be excessive.
3. The brand and material of the toast box are different, and the baking time needs to be adjusted according to the usual situation of baking the toast.
