Arran pilot is one of the most popular first early potato varieties amongst amateur gardeners and this has been the situation for 30 years or so.
There is no doubt that this variety has a very short shelf life, ten days at the most. But when eaten within a couple of days after they are dug up the flavour is supreme,
quite delicious. That is the best way to cultivate this variety so only grow as many as you can eat almost immediately they are harvested.
