In a large bowl- add 1 tsp of yeast, 4 tbsp of sugar and 1 cup of warm water. Stir until dissolve.
Add 6-7 drops of food coloring if you want a darker shade, for a lighter shade, add 2-3 drops
Add half of the flour in the bowl and mix it well. Then add the rest of the flour in. Give it a good knead and let it rest in the room temperature for half an hour.
After letting the dough rest give it another good knead. Cut it into small pieces. 4-5 pieces of the dough will make a set of roses. To make the core of the rose, get a piece of dough half the size of the petal pieces and roll it into a cylinder. Cut it into half and spread the top to give it the rose look.
Place the roses in the steamer and steam it for about 14 minutes.
Wait 3-5 minutes after turning off the heat to take out the buns.
