Buy local, buy British, ask questions, says CofE national rural officer August 18, 2015 by Fulcrum "It takes roughly 10 litres of milk to make 1 kilogramme of hard cheese such as cheddar, so it is important that we try and buy as much cheese, yoghurt and butter that is produced in the UK from British milk. Roughly half the milk produced in the UK is used to make dairy products. Canon Jill Hopkinson. Church of England. 17 August 2015 FulcrumShareTweetShare
