Sium sisarum (skirret, crummock) is a perennial plant of the family Apiaceae sometimes grown as a root vegetable. It has a cluster of sweet, bright white roots which are similar to sweet potatoes, but longer (15-20 cm). Skirrets may be boiled, stewed, or roasted. The woody core is inedible, and should be removed before cooking because it is difficult to remove after.
