Chinese Steamed Buns (mantou)

I have apparently made this before and this version one doesn't use dried milk. The metric recipe ratio comes from the China Sichuan Food website. I'm not sure why the measurement for liquid milk was done in grams, so I used a kitchen scale and measured it out by weight. My Imperial conversion of the recipe is as follows:

Makes 8 buns

Ingredients

10 oz (by weight, roughly 2.25 cups) unbleached all-purpose flour
2 1/4 tsp active dry yeast
2 tbsp organic granulated sugar
1/2 c whole milk, warmed to 110 degrees F
1/4 c water, warmed to 110 degrees F

Directions

1. To ensure that your yeast is still alive. Proof the yeast in warm water with 1 tsp of sugar. After 10 minutes, if the yeast is foamy then it is still active.

2. In a large bowl, add flour and stir yeast water with chopsticks to combine.

3. In a small pot, heat milk and remaining sugar until the sugar dissolves. Remove from heat before the milk comes to a boil. Let cool to 110 degrees F before adding it to the flour.

4. Gently knead flour into a ball and cover bowl with a plate. Let rise for about an hour until it has doubled in size.

5. Roll dough on a silicone mat or on a lightly floured surface. Divide dough in half. Roll out each half into a log and use a dough scraper to divide the log.

6. Dab a little olive oil to the bottom of each bun before placing onto a 2" square of waxed paper. This step is optional. It helps you remove the paper after the buns are steamed.

7. Bring a large stockpot with a steamer basket set inside to a boil. Add enough buns so that they are spaced at least 1/2" apart. Steam for 10 minutes. Remove from heat and enjoy.

These are best eaten right after they're cooked, otherwise the buns will get hard if left out too long.
