Thanks for all the info Trill, really interesting to read a farming perspective, we live in dairy country now and I'm learning alot from lots of people I work with who are farmers too.
We were using the Aldi butter but recently have just been using block butter (still Aldi) and covering it and leaving it in the pantry. It's still pretty cool here at the moment but not sure what we will do in summer when it melts too much! It's amazing how much nicer it tastes!
