It worked back in India and my mom used to do all the time. Malai was my nemesis and I'd drink milk strained twice, just to make sure no tiny bits of malai left in milk. LOL. So naturally I never enjoyed this treat.
Oh wow. I thought this was just my personal quirk. I absolutely cannot tolerate malai in my milk. I (involuntarily) spit the milk out if the mouthful happened to have even small bits of malai.
