Take 50 ml lukewarm water in a bowl. Add sugar and yeast to it. Stir and keep it aside until it froth.
To make the puree of Spinach and Beetroot, blanch both the vegetables separately and then grind them to paste. Transfer them to a bowl and let it come to room temperature.
In a large mixing bowl take flour, salt, milk powder, oil and add activated yeast solution. Start kneading.
Divide the mixture into two equal portions.
Add beetroot puree to one half and spinach puree to the other half. To make the smooth and soft dough I added 10 ml water to each mixture.
Knead both the doughs for 5 min and keep them in a greased bowl covered with cling wrap until double in volume.
When the dough is double, punch it to release the air in it.
Using a rolling pin, roll both the dough into a rectangular sheet.
Place one sheet on another and roll them like a swirl.
Grease a 9x4x4 bread tin with butter. Now keep the shaped bread dough into this greased tin with seam side facing downwards.
Cover the dough again with cling wrap and let it rest until it doubles.
Meanwhile, preheat oven at 200 °C for about 10 minutes.
Now bake the bread in preheated oven for 35 minutes.
After 35 minutes take the bread out of the oven. Demold the bread and keep it on a cooling rack. Brush the bread with butter and let it rest for minimum 2 hrs before slicing.
