For those who may not know much about these two,
Moie-moie is white inside but can have a small amount of purple/red,its very firm when cooked,great for potato salads.
Ive found it to be a very reliable cropper
Moie-moie again is a potato that gives great yielding crops of mostly solid purple colour inside,some plants can throw a bit of white which is something i'm trying to select out.
Taste is rather earthy which i like myself but my kids are not so keen on
(fussy little so and so's)
