非常棒的包子

我做了2次，一次用普通面粉做叉烧馅包子，所以包皮会偏黄。第二次用特级白包粉（pink horse brand）做长豆馅包子，会比较白哦！口感的话，没有分别！

• 500 gm Pau flour/Hong Kong flour
• 2.1/2  flat tsp yeast

4. Cover dough with a wet cloth, place in a warm place and let dough prove till double in bulk, around 1 hr to 1.1/2 hr.
5. Knock dough to expel some air, knead for some time.  Roll out onto a floured board.  Weigh out 50 gm dough, roughly form into a ball.  While you are working with a ball of dough, cover the rest with a damp cloth  to prevent them from being exposed to air and getting flaky.  Makes  18 pau.

7. Set them aside for another 15 mins, and meanwhile prepare the steamer with water.
8. Steam pau under rapidly boiling water for 10-12 mins.
9. Quickly and carefully remove the steamer cover so that condensed steam will not drip onto the pau.
10. Remove the pau from the steamer rack and serve hot.
