What are Fingerling Potatoes?
Fingerling potatoes are a family of heritage potatoes which naturally grow much smaller than conventional potatoes. They also tend to be elongated and slightly knobbly, making them very finger-like in shape. The unusual looking, flavorful potatoes can be used just like regular potatoes in an assortment of roasted, broiled, baked, grilled, or boiled dishes. Many grocers stock fingerling potatoes in season, and they can also be grown at home, in temperate climates.
Like other potatoes, fingerling potatoes are tubers, and their roots can be found in South America, where Native Americans first domesticated the potato. Just as there are numerous conventional potato varieties, there are a wide range of fingerling potatoes on the market. They run the gamut from creamy white to rich purple, and they come in waxy and starchy varieties, suitable for different dishes.
Some people confuse fingerling potatoes with new potatoes, which are young potatoes harvested before they fully mature. While young potatoes and fingerling potatoes share a small size and thin skins, fingerling potatoes have a more complex flavor, and they are fully mature. Just as is the case with regular potatoes, fingerling potato farmers allow the green upper portion of the plant to die back before harvesting fingerling potatoes.
When selecting fingerling potatoes in the store, look for specimens without obvious soft spots or mold. Dirt is not an issue, as the potatoes can simply be washed when there is need for them. In a root cellar, fingerling potatoes can keep for months, although they may undergo flavor and texture changes. They can also be kept in a cool dry place for a few months, depending on how heavily the ambient temperature fluctuates.
Many cooks use fingerling potatoes in dishes which will showcase their small size. Potato salads may feature half-fingerlings, for example, while the potatoes roast and broil very well for side dishes. They are usually eaten whole, skin and all, since the skin is thin and very tender.
To grow fingerling potatoes, plant seed potatoes in rows in loose, loamy soil after the last risk of frost has passed. Leave lots of room between the plantings, as many fingerling potato varieties like to spread out. Make sure to keep the soil well moistened, and mulch after the plants have established themselves to help retain water in the soil, keep weeds down, and keep the tubers from getting too hot while they grow. Once the plants have died back, harvest the tubers, brushing the dirt off but not washing them until they are going to be cooked.
