When I was a kid living in Brooklyn a million years ago, I had my mother buy, Horlicks (brand)
chocolate malted powder. I put in on EVERYTHING! Even ate it straight out of the jar.
They (Horlicks) are probably long gone but, you can still find Carnation (brand) malted powder.
Does anyone remember Horlicks products? Thats the brand that was used in all the "candy stores" in the NY area to make malts.
