Heat up the milk until it’s lukewarm (37ºC/98ºF). Crumble the fresh yeast into your mixing bowl and pour in the heated milk. With a spatula stir it together until the yeast has melted. (If you are use dry yeast, let it bloom in the warm milk per instruction of the pack)
100 g whole milk, 15 g fresh yeast
Add the granulated sugar, all-purpose flour, tangzhong, egg, cardamon, salt and using the dough hook, mix the dough on low-medium speed until it is all hydrated and there is no dry flour left. Then mix further for 4 minutes on medium speed.
30 g granulated sugar, 280 g all-purpose flour, 1 teaspoon ground cardamom, 1 large egg, ½ teaspoon salt
Continue on medium speed and add the butter in two parts. Add the second part of the butter, once the first part has mixed into the dough.This part looks messy but don’t worry. Once the second part has incorporated, scape down the sides of the bowl and keep mixing the dough for 8-10 minutes. It should end looking smooth and glossy. This dough is very nice and soft so it’ll therefore be tacky when touching it.
50 g butter
Add the dough to a clean bowl, with a bit of vegetable oil, and cover the bowl with cling film and a tea towel. Place it in a warm room temperature area in your house. Let it rise for 1 hour. See FAQ above for overnight rising.
