I've been consistently disappointed with the varieties of potatoes available at SF farmers markets. At Alemany the potato guy sells just the stuff I can get at safeway: yellow fin, idaho, fingerling, reds, purples. Sometimes I can get German butter potatoes at another stand.
Why the dearth of heirloom and other potato varieties? In a city where I can find 4 types of radichio at the corner store there are no heirloom potatoes in the farmer's market?
In particular i'm looking for Nicola potatoes - A thin skinned, oblong, waxy, extremely yellow fleshed and sweet potato with a flavor that's quite different form regular potatoes. They're waxier then even red potatoes and the sweetness reminds me of carrots. As a plus it's a low glycemic potato.
The names "Nicola" and "Linda" are German - for some reason German potatoes are mostly named after women. I don't know what the English equivalents are.
But I'm interested in sources for potatoes from central and eastern Europe. Are there secret stores in the Richmond? A potato "underground" source?
