JUST a year after launching her business, Primal Joy Foods in Stonehouse - making healthy snacks for people with food allergies and intolerances - Sarah Mace's tasty enterprise is booming. Thanks to an investment of almost A 3,000 from Stroud District Council through its Food Grants scheme, Sarah has taken on a new member of staff, bought larger equipment to increase production and moved out of her kitchen and in to a small business unit close to her home.
