Veganism came relatively late to Scotland, although the legendary cafe in Edinburgh, Hendersons, had followed the London based Cranks wholefood vegetarian example in the early 1960s. The Ceilidh Place in Ullapool, followed with a give peas a chance demi vegetarian version.
It wasn't until the 1990's with Royal Deeside's Inverdene vegan guesthouse, run by Green Party Vegan Steve Campbell, and Taigh Na Mara Vegan Guest House in Ullapool, with it's vegan haggis and Rainbow's and Wellies Scottish Vegan Cookbook, that Scottish Veganism began to take hold.
Ironically it was Glasgow that took plant based cooking by the horns rather than vegetarian friendly Edinburgh. Glasgow now boasts at least five 100% vegan establishments and in early 2013 was nominated in the Vegfest UK AwardsBest UK City for vegans.
There are now 4 versions of vegan haggis commercially available, the most famous being McSweens vegetarian haggis.
