Macsween of Edinburgh has developed a microwaveable haggis product that it hopes will account for 15% of its sales within three years.

Cooking in just one minute, the two haggis slices come in a pack that can be placed straight into the microwave. It will go into Morrisons' Scottish stores and 75 Waitrose outlets later this month.

There was demand for a convenient version of the traditional product, said director Jo Macsween. "So here it is, no additions no subtractions just tasty, traditional haggis."
