Book / gifts / vouchers
Give your loved ones the gift of knowledge with a butchery or sausage making class voucher. They may think they know everything but you and I know that isn't true - and you should see what happens in the cool room when people start connecting with their inner butcher...
Alternatively, if they're total smarty pants and really do know much more than you, give 'em a gift voucher for our gorgeous tucker. At least they can't make you feel inadequate when their mouths are full.
You can also give them a nice bag to hold all their loot. Or give them the full catastrophe - a voucher, a bag and a teatowel to keep things tidy.
