I bought some Salad Blue potatoes at Borough Market the other day, and just ate them (roasted). I was surprised by how disconcerting I found the violet-coloured flesh. After a few mouthfuls, you get used to it, but at first, they look really unappetising. They just tasted like potatoes, though. If anything, they were on the bland side. Next time I buy heritage potatoes, I’ll pick them on the basis of flavour rather than novelty colour-scheme.
