Long before the days of the 3 in 1 beverage mix, things were done the traditional way. Here is a Horlicks mixer from colonial Singapore in the 60s. It comes with a plunger and gives exact instructions on how Horlicks should be made. My favourite part is point 3 - AGITATE BRISKLY WITH THE PLUNGER. It has such a nice frantic ring to it. Oh the days of yore !
