Sift flour through a fine sieve mesh into a mixing bowl
Add the rest of dry ingredients into the bowl
Using a dough hook, on slow speed, add egg, milk, condensed milk to drymixture and mix until cohesive dough starts to form, about 1 minute
Use rubber spatula to scrape downsides of the bowl if necessary
Increase speed to medium-low, add butter, one piece at a time, and mixuntil butter is fully incorporated
Continue to mix the dough until it is smooth and elastic, about 2minutes. Make sure there is no dry flour remains on the bottom of the mixing bowl. Do not add more flour to the mixture because the dough islightly wet
Transfer the dough to a lightly greased large mixing bowl and use yourhand to knead the dough a few times to form a smooth round dough
Turn the smooth dough seam side down. Cover the bowl tightly with plastic wrap and let the dough rise untilit is double in size, approximately 1.5 to 2 hours. Do not rush this proofingprocess or you’ll end up with heavy, not fluffy rolls
In a mean time, grease your baking pan
When the dough is ready punch down the dough and carefully transfer it to a lightly-floured counter. Divide the dough into 8 equal pieces (about 2.6 ~ 3 oz each)
Work with 1 piece of dough at a time.Cover the rest with plastic wrap if you need sometimes to form each small dough
Stretch the dough by using your fingers and pinch the edges together atthe bottom to form a smooth dough
Place the dough seam side down back on the counter and use your hand todrag it in small circle to create a smooth round ball
Then transfer the round ball, seamside down, to an already greased baking pan. Repeat for theremaining pieces
Arrange them nicely in the pan then lightly cover with plastic wrap and let them rise until almost double insize. Make sure they don’t rise above the rim of the pan
Preheat oven to 350F
