That may have been it @lovinglife .Did she used to add milk to the butter? You can melt butter and add full fat milk to it and whip to turn it back into cream - would it be that?

In the days when I ate bread etc. I favoured unsalted butter and bought from British farmers. Now I don't eat carbs, butter is only used for cooking or put on vegetables just before serving, and as long as it's from British farmers I don't have a preference.
I like Anchor and I never use spreadable , if there is an offer on double cream I make my own , normally get my Anchor from Costco and freeze it
Very easy to do - shove your cream into a mixer and beat the life out of it until it separates- I’ve done this on a few occasions inadvertently when whipping cream and forgetting about it lol, you need to wash the buttermilk off the butter - the buttermilk you’ve left behind in the mixing bowl is great for tenderising chicken breasts - buttermilk chickenMaking your own is imho most impressive!
