Chop the veggies roughly. Steam/Pressure cook till the veggies are just cooked.( Don’t overcook)
Run for a few minutes in the blender till smooth. Strain or don’t strain through a sieve(I haven’t).
Add 1tsp butter to a pan. Add some part of the pulp to it.(Refrigerate the leftover pulp to be used later)
Add sufficient water to make a soupy consistency(to your liking). Add salt, little sugar and freshly ground black pepper powder. Bring it to a boil. Serve piping hot.
