One of the brilliant things about living in the UK and especially in the South West is that there is a dedication to keeping the local farm alive. Moreover, many of these local farms go as far as to go organic and thus contribute to sustainable agriculture and to keeping our environment a nice place to be.
I am also surprised at how affordable some of these products are as well as the quality that you get. Granted it means sometimes having to be creative and cooking with new vegtables and cuts of meat. The flavor of the food is the true sell for me. The cauliflower (which comes in green, white and even purple varieties) is so pure and needs nothing to it to be tasty. Carrots that are so sweet they don't even need ranch dressing, potatoes that taste like potatoes and tomatoes that taste of the sun (in the summer of course).
Anyways... my whole point with this is to create a list of local suppliers of good or "slow food" so that people can find them local to them. So please put a link (if they have a website), address or phone number and what you like about them. It's kind of like a Rick Stein's good food guide on UKY.

I have to put a plug in for
www.rodandbens.com who won the best egg in the UK category. They have a box scheme that covers Exeter and Exmouth. I go to school with Ben's wife.

I get a bi-weekly veg box from
http://www.riverford.co.uk/en/ and they work with local producers to deliver UK wide. Never had a disappointing box!
I also do a monthly meat box from
http://www.wellhungmeat.com/ Their pork is award winning and I can't think of anything bad to say about the meat we have had. They also do cottage lets on their property.
Well those are my contributions. Feel free to add little local shops as well!
