After 1:30 hours, the dough must have been doubled in size.
Knead it again for a minute.
Divide dough in 2 equal proportions.
Take one portion and roll it round in a circle of about 10 inches diameter. Dust flour whenever needed.
Place this circle in a baking tray lined with greased butter paper or silicon mat.
Take a small bowl (of about 3 cm) and place it in the middle of your rolled-out circle, pressing it gently to create an indent.
Remove the bowl and place some potato stuffing over there.
Also put the stuffing in a ring shape around the central stuffing at some distance, as shown in picture.
Brush some water on the naked part of the round roti.
Roll out the 2nd part of the dough to the same diameter and place it carefully on the first circle having stuffing.
Join the 2nd part with the first part where the water was applied. (Video is attached to this post for better understanding).
Seal the edges properly.
Using a sharp knife, cut into 4 parts taking care to leave the middle indent of 3 cm as it is.
Divide each quarter into 6 equal petals making total of 24 petals.
Working gently, twist each petal.
Press the edges.
Cover the bread with a clean cloth for second proofing for 30 minutes.
Brush the entire bread with milk (mixed with sugar)
Sprinkle some black sesame seeds in the middle round bump giving the bread a sunflower look.
Bake in the preheated oven @180°C for 18-25 minutes or until the top is golden.
Brush the butter over the hot bread.
Cool on a wire rack for 10 minutes.
It's ready. Enjoy
