Looks like a potato & tastes a bit like a cross between a water chestnut & a pear! Originally from South America, & distantly related to sunflowers, the yacon is a perennial plant producing huge, fuzzy green leaves & attractive yellow flowers. It grows a bit like a Jerusalem artichoke, producing a good crop of very sweet, crunchy, but also nicely juicy tubers. Try them raw in salads or instead of water chestnuts in stir-fries. What's more the yacon's sweetness comes from inulin which is an indigestible sugar, so despite the sweetness it has almost no calories! & the leaves can be used in cooking as wraps, like you would vine leaves. Pale-skinned varieties are available, but we've selected this violet-skinned one, which has enhanced cold tolerance. Well worth a try!
