Heritage vegetable review
Edzell Blue   Edzell Blue potato

Age: before 1915
My supplier: home-saved tubers, originally from Waitrose
Pros: gorgeous colour, trouble free to grow
Cons: temperamental to cook

Edzell Blue is certainly a looker, there's no disputing that. The colour is magnificent when newly harvested and scrubbed ... really amazingly vibrant purple. It dries to a muted deep mauve which has an almost metallic sheen. Very pretty indeed. And when you cut it open the flesh is a pure bright white and looks lovely in contrast to the skin. The skin is shiny with freckles and some variation in colour. Tubers are a bit smaller than a modern spud and usually smooth and rounded with quite deep eyes.

Presumably it originates in Edzell, Angus (Scotland). It was first referred to in 1915 but is thought to date from the 19th century.

The flavour is nice. It's not the most wildly exciting flavour I've ever tasted in a potato, but it is nice. Mild and delicate. Texture tends towards the floury end of the spectrum.


There is a definite art to cooking it (no doubt that's one reason it's rarely offered in the shops) and I haven't mastered it myself. It tastes lovely as a new potato when it's small, but boiling it is not an easy process because the flesh seems to absorb water more than most varieties. Unless you get the timing absolutely right it falls to bits. Mash is an option, but it tends to be watery for the same reason. Baking is less hit and miss, although the spuds are on the small side for baking (not that it bothers me, 'cause they need less baking time if they're small) but they don't really seem suited to this either. They have too much dry matter in them and go very floury, and the baked flavour isn't very inspiring. The skins go extremely crispy and leathery and take a lot of chewing. Roasting seems to be the most satisfying option, and very nice it is too. Steaming might also work well. But all in all Edzell Blue is not what you'd call versatile.

And if you were hoping it might keep that colour when you cooked it, you'd be disappointed. The ice white flesh stays the same but the skin goes a brown colour like any other potato. And if you boil it the water will go dark green as the purple colour dissolves. Good old water-soluble anthocyanin pigment.

Edzell Blue is a Second Early type. The plants grow fairly upright with lightish bright green leaves, and were trouble free in my garden. They produce very pretty pure white frilly flowers with golden centres, which are really lovely. The flowers drop once they've faded and don't tend to produce seedballs. It was the first variety I harvested (June) and the yields were pretty good. No blight, because they are harvested before it strikes.

So on the whole my impressions of Edzell Blue are positive. It's not one of my special favourites, but that's partly a matter of taste. It's very nice and well worth growing, if you don't mind a few frustrations in the kitchen.
