Teenager clinches Waitrose deal - and there's nothing jammy about it.
Fraser Doherty, 18, of Edinburgh, created a range of "SuperJams" which will be stocked in 130 Waitrose stores across the UK from March.
Using fruits high in antioxidants, such as blueberries, raspberries and cranberries, the teenager adds grape juice to sweeten the fruit instead of refined sugar or artificial sweeteners, which can make up as much as 70% of the ingredients in some traditional jams.
This means the preserve is lower in calories and sugar and has a lower Glycaemic Index than others.
Fraser - now studying accounting and finance at Strathclyde University - began making jam aged 14, using his grandmother's secret recipe.
Jam tycoon in the making ... Fraser Doherty, 18, who yesterday spoke of his joy at becoming one of the youngest entrepreneurs ever to supply a UK supermarket
