Well I tried... 

Just lifted my first International kidney plant for dinner and they've got scab again.  I'll pull one of the pentland javelins later this week and see if they're as bad.

Does look like spuds are off the menu until I can sort the problem out though.

Just peel the skins off and the potatoes are fine to eat.

Peel a new spud   Iain shame on you !!!   

Im looking for bakers and new spuds that taste like they should - normal boiled pots I might as well pick up form the supermarket - I can't really tell the difference once they're covered in gravy.

Am I right in thinking its just the poor soil condition  (too alkaline? ) that causes it.  I have nasty sandy soil. The solution being as always more pooh

Hi Lardman
Lime and potatoes don't like each other and will result in scabs.
The scab could be caused by spores in your soil which can cause scab aswell.
Go on peel them and eat them

[Lardman]

Theres no skin as such to peel... Id eaten them before I posted  bit of scab never did anyone any harm - did it? Not as nice a flavour as I remember though 

T.O.B.N.D.'s spuds are fine, he grows vast amounts - hes been cultivating the ground for 30 years so I expect its in slightly better condition than mine.

Well I've lifted a pentland javelin.. Id say its just as bad if not worse than the international kidney..

Well 2 different varieties with the same problem would make it something in the soil.
Your PH could be too alkaline or you could have suffered from dry warm conditions at tuberisation which can cause scab to be formed.
