The roghan needs to be strained to ensure a smoothe flowing consistency that is free of lumps. The inspired resourceful sieve to strain the roghan is made by tying muslin at two ends with sticks.
The roghan is poured into the muslin, deftly twisted it covers the roghan completely. The muslin ends are tied to sticks, for ease of manipulation.The muslin sieve is then twisted and turned, tightening with each squeeze, forcing the roghan out.
The sieved roghan free of any lumps or particles is ready for use.
