Re: Smarts drink tea or Drink tea makes smarts
I presume they meant sterilised milk.
UHT is not the same stuff (if memory serves), as it involves a different process and timer at temperature. As a kid, sterilised was also a crown cap bottle rather than foil lid or carton. If I could be bothered I'd link to it, suffice to say that they taste totally different from proper milk.
Which is semi skimmed.
