Thanks for that info, Martin.  I hope I don't need to put any further info on my labels than at present.  I checked with my local Trading Standards office and they were helpful.  As I only sell my produce once a year and direct to the customer from outside my property I only need to list the ingredients (I do it in descending order, listing the greatest first), give a best before date and a contact address to comply with their requirements.  I do have to comply with regulations when labelling my preserves as "extra jam", ensuring the proportion of fruit is as stated in the blurb.  If I were to sell via a shop, at a Farmers' Market, etc then I would need to get the gadget that measures sugar content percentages and probably get my kitchen inspected and maybe even a Food Hygiene Certificate.  I can't justify the expense of buying one of those gizmos or be bothered with all the inspection/certification.  I'm careful with sterilising jars and lids.  I've had no complaints and have managed to bring up two children and feed them and my husband for the last 40 years without poisoning them!  EU please leave us cottage smallholders alone!!
