For my next trick...

Butter! 

I ladled off and then froze the cream from the top of the last four churns of milk. Today I made it into butter. 

The last time I made butter was in primary school, and brother #1 remembers us all making it at home when we were children. That makes it more than half a century since I made any. (How did I get that old?) 

It seems silly to have been buying butter when I collect free milk twice a week. I don't know why I've not made it before. 

It is a simple - if lengthy - process. It seemed to take an absolute age for the cream to thicken in the stand mixer, so I got my hand-driven egg beater out and gave it five minutes of hard whizzing to get it moving. That did the trick and before too long - once back in the stand mixer - there is was: a big blob of butter washing around in a pool of buttermilk.

I got 275g of butter from 1 litre of cream. It tastes amazing. Unsalted. And a jug of equally delicious buttermilk. 

Yum yum yum.
