Tangzhong- in a saucepan: add flour, water, milk and mix everything together. Turn the heat to low-medium. Use a spatula or whisk and stir frequently to prevent burning. Cook for 3-5 minutes or until the mixture thickens (reaches to 150°F). Set aside until ready to use.
In a bowl: mix the yeast and coconut cream (warm 110°) Let sit for 10 minutes.

Transfer the dough to a working surface.Then, divide the dough into 12 pieces (70g-73g each). Highly recommend using a food scale for your dough.
Flatten and fold the edges together then seal them to form the roll. Gently shape each piece into a smooth ball (Watch the video for reference). Transfer the rolls to the greased pan.
Second Dough Rise: cover and let rise for 2 hour or until it doubles in size. Optional: place in cold oven with the light on. Remove pan when ready to bake.
Preheat the oven to 320°. Sprinkle or sift cornstarch on top of the rolls (this will prevent it turning too brown). Bake for 20-22 minutes or until lightly golden on top. It took me 22 minutes.
