These light, buttery buns are a perfect match for burgers, pulled pork or for the best ever bacon roll.
Put the ingredients into a sauce pan and whisk together. Put on a medium heat and whisk constantly until it reaches a thick paste. Only takes a few seconds to reach a choux pastry-like consistency. Put into a bowl for use later.
Heat the milk to 95° F and stir in your yeast. Let stand for about 8 minutes.
Combine the flour, sugar and salt in the mixer bowl and give a good mix. Put on your dough hook and put the bowl on the mixer. Put the mixer on a low speed and add the yeast mixture letting it mix for a few seconds.
Now add the tangzhong paste followed by the egg and egg yolk (best if at room temperature, not chilled). Increase the mixer speed slightly (remain below medium) and mix until thoroughly incorporated. Scrape down the sides as required.
Add the softened butter one tablespoon at a time allowing it to incorporate before adding the next tablespoon. Continue to let the mixer knead the dough until all of the butter is incorporated and the dough is nicely smooth. Expect this to take about 10 minutes.
Take the dough from the mixer bowl put it on a lightly floured board. Gently stretch and fold it in from each edge to make a nice ball. Pull from one edge and then rotate 90 degrees and continue for two rotations. Turn the dough over and gently pull the dough toward you keeping it in constant contact with the board to fold it into itself. Rotate 90 degrees and keep doing this until you have worked it into a nice ball shape.
Put into a bowl lined with lightly greased baking parchment and cover with a damp towel. Place in a warm area for 1 to 1½ hours to rise, until doubled in size.
Punch the dough down and put in on a lightly floured board. Divide the dough into six even pieces using a scraper. Each piece should weight about 105gm.
As before, gently pull and fold each piece of dough into the center creating a ball. Put onto the board and pull the dough across the board (keeping the dough in contact with the board always), turn 90 degrees and repeating. Do this four times until you have a nice tight ball of dough.
Place the dough on a lightly greased baking parchment in a baking tray giving plenty of distance between each ball (at least 2 - 2½ inches).
Place a lightly greased piece of baking parchment over the top and cover with a damp, warm towel. Allow the dough to rise in a warm location for 1-2 hours until doubled in size again.
Brush the dough lightly with the egg wash. Bake at 350° F for 16-18 minutes until a deep golden brown. If the tops start to become too brown, then covert with foil.
Place on a wire rack to until completely cool and then wrap in cling film or foil to keep fresh. Use within two days or freeze immediately.
In my first effort with this recipe I found the buns browned too quickly. I've watered down the egg wash slightly and reduced the oven temperature by 25 degrees. I covered them with foil at 11 minutes to stop them browning further.
I also found the buns to be a little bit dense. Now you want a certain level of density to handle the juicy burger and sauces, but this could be a bit lighter. I believe the key to this will be to do use smaller portions and let them rise longer to the desired size. The extra rise should ensure a lighter texture.
