1/2Ctangzhong(to make it, combine 1/3 C flour and 1 C water in a medium heat pan and cook until the mixture thickens)
For the glaze:
Vegetable oilneeded amount
2Cconfectioners sugar
1tbspwater
1tspvanilla extract
Instructions
In a big bowl, mix the milk with the sugar and yeast. Let it sit for 20 min.
Then add in the butter, the salt, the egg and the 1/2 C of tanzhong already cooled and mix with a wooden spoon.
Add in the flour and salt and start kneading until it´s all incorporated.
Place the dough on the work surface and keep kneading for about 15 min. until you get a soft elastic dough. (this whole kneading process can also be done in a standing mixer with the kneading hook attached)
Form a ball with this dough, spread some oil on it and place it in a bowl which we will cover with plastic wrap or a kitchen towel.
Now let it rest for 1 hour or until it doubles its size.
Pinch the dough and let it rest again, this time for 30 min.
On the working surface, roll out the dough until it is 1/2 inch thick and cut it out with a donut shape cutter (you can knead and roll out again the leftover dough but the resulting donuts won´t have the same consistency).
Place the donuts (the small bits of the holes can also be used) on a previously greased baking sheet and cover them with plastic wrap or a kitchen towel and let them rise 1 more hour.
In a medium size pot heat enough oil. Once the temperature is right deel fry them until they turn golden brown.
Once they are done, place them on a plate with some absorbing paper underneath.
For the glaze, mix all the ingredients, and once the donuts are cool glaze them. And you´re done!
