To make the buns we start by activating the yeast. Take a bowl and add the warm water and sugar and add the pack of yeast. Now let this bloom for about 5 to 10 minutes in a warm place.

Once the yeast has bloomed add the oil, tahini, backing powder and flour to the bowl and mix until you get a soft and dough. I let the food processor mix the dough for about 15 minutes or so. You can also kneed it by hand.

Now add the ball of dough to a bowl, cover it and set it somewhere warm to let it rise for about 60 minutes. After this roll out the dough till its about half an inch thick and cut out circles using a cookie cutter or a big mug. Cover the tops with a bit of oil and fold them in half.

Now place them on a piece of parchment paper in a steamer, cover it with the lid and steam the buns for about 15 minutes. Remove them from the steamer and they are ready to be filled with whatever your heart desires.

Add all the ingredients to a bowl and whisk it all together. Now pour them over the slices of tofu you've put in a container or sip lock bag, give it a good shake and set it in the fridge to grill or cook whenever you want to use them.
