I bought some blue Scottish ones this year - never again, heritage or not
Shame I don't remember the variety but all they were good for was deep fried thinnest crisps! Once hot water as far as touched them they fell apart into a starchy sauce, maybe there are for soups
Will have to do better research next year before I buy as the labels in Freuchie don't really say anything...Maybe on-line is better. Apparently the guy who supplies Freuchie and T & M is also in Fife and you can buy on-line.
