About Sunchokes
Sunchokes, also known as Jerusalem artichokes, are small and knobby, similar in size and shape to ginger or small potatoes.
They have a slightly sweet and nutty flavor, with a crunchy and slightly starchy texture.
Sunchokes can be found in many grocery stores and farmers markets during their peak season, which runs from fall to early spring.
When purchasing sunchokes, look for firm, dry, and unblemished roots with a fresh and earthy scent
