An old widow named Laycock used to make icecream at her home opposite St Pauls church Ossy, and sold it from a chest freezer parked in her vestibule. That was creamy yellow too, but sometimes had lumps in which was the 'skin' caused when she boiled the milk.
There was no 'pasteurised' or UHT, and herds weren't TB vaccinated.
The option to whole raw milk was sterilised milk which tasted very different.
