From a batch of raw (unpasteurised) double cream from Helsett Farm in Cornwall. I allowed the cream to ferment for 6 days in the fridge at around 3℃, and then at room temperature (20℃) for another 6 days. I whipped it, strained the buttermilk, and served the first serving. Then I used the butter at various intervals over the next four days, before wrapping it and storing it the fridge for some long ageing. Two weeks have passed, and the butter has a deep savoury smell and taste.
The milk was given by Ayreshire cows to an automatic ‘self-milking’ machine on May 16th, 29 days ago. Eighty litres of milk were skimmed to produce six litres of double cream. I don’t know the fat content, but it was definitely not low. I have stopped serving the butter to the public, and will continue to monitor and eat it until it tells me not to.
I recently bought the bowl in the picture from a local potter and gardener called Jan Pateman, who has a stall in Herne Hill Farmer’s Market.
