That's what the last batch of potatoes came out as. I also cooked up the previous batch last night which was delicious. The only problem was peeling them because they were so small. If the skin would have been thinner I bet they would have been delicious just cooked as they are.
Well, there's another problem. Labeling. I am pretty sure that none of the potatoes I harvested were the ones I originally thought they were. For example, the first batch I thought was Dark Red Norland probably weren't since they were purple. The second I labeled Rose Finn Apple but I'm pretty sure this isn't the case as the harvest of the third one fits that description much better. I have some variety called 'Butterfinger' listed in my notes but that could just be a Freudian slip. So, to review what I actually think is the case:
First potato - unidentified purple variety
Second potato - Butterfinger
Third - Rose Finn Apple
I can't complain really since I got them free from an anonymous gardener who left them in the potting shed. I have high hopes for the Rose Finn Apple, I hope they are as delicious as they are visually pleasing.
