Fingerling are long, slender, small potatoes.
There are many different varieties. The skin colour can be anything from buff to purple.
They are usually 1 to 2 inches (2.5 to 5 cm) wide, and 2 to 3 inches (5 to 7 ½ cm) long, though some varieties can be up to 10 inches (25 cm) long.
They tend to be waxy, and good for salads and roasting.
They are expensive compared to other potatoes.
Salad potatoes, new potatoes
Many potatoes were originally the size of what we now call “Fingerling Potatoes”, before centuries of cultivation selectively bred them to be larger. Now, potatoes this size are considered a novelty; they started to become fashionable in the food world towards the end of the 1990s.
Sometimes just referred to as “finger potatoes.”
