Steamed (pork) buns

equipment: stand mixer bamboo steamer and pan of water for it parchment paper get: 6 oz flour, 2 tbsp corn starch (to emulate cake flour) 2 tbsp powdered sugar 1/2 tsp baking powder 1/4 tsp salt 1/4 cup warm water 1/4 cup warm milk 1/2 tsp yeast 2 tsp oil filling, from some other recipe, not my problem, I'm just a bun recipe do: Combine the yeast, water, and milk in a small bowl. Stir together and let sit for 10 minutes to activate the yeast. Meanwhile, use a little whisk to combine the flour, baking powder, sugar, and salt in the bowl of your stand mixer. Start the kneading hook on the dry stuff and pour in the yeast mixture and the oil. (Note: The wet/dry ratio is still a work in progress. Fuck with it.) Knead for 10 or 15 minutes until the relatively dry dough can pass a windowpane test. Rise for 1 to 2 hours in an oiled bowl under a wet towel. During this time, cut 6 parchment squares about 3x3 inches. Punch the dough back down, weigh it, and chop it into 6 equal-weight pieces. For each piece, roll it out on a lightly floured surface, with a rolling pin, to 4 - 5 inches diameter. Make the edges thinner. Spoon 1 - 2 tbsp filling into the center, then make about 8 pinches around the edge, join the pinches together at the top, and twist them together to make a seal. (If the dough is too thick at the top, you'll make a giant puffy top.) Place this on a parchment square and into a bamboo steamer tray. Let it "rest" for another 30 minutes. It's really rising again, in the steamer. Boil water in a pan over medium-high heat, put the steamer on, and cook for 10 to 12 minutes. Remove and let it cool to a safe temperature for about 15 minutes. Eat! Notes: 1/4 cup water + 2 tsp milk was laughably too little liquid -- try 1/2 cup total now too wet. maybe like 6 oz flour instead of 1 cup. i accidentally used baking soda instead of powder, so they turned brown like a pretzel. don't do that! pinch of salt wasn't enough -- maybe 1/4 tsp? they puff quite a bit! don't be afraid to overfill, and add some sauce.
