Yam Bean

By

Yam Bean (Jicama, Mexican Water Chestnut or Chop Suey Bean)Yam Bean (Web)

Pachyrrhizus erosus

Origin: hot, humid tropical Central America

Plant: Sept – Oct

Harvest: July – Aug.

It takes 4-7 months to maturity depending on day-length hours. At the time of maturity, the vines will flower and produce many inedible pods (the flowers are also inedible)

– the mature seed contains the poison, rotenone, used as an insecticide. Jicama’s starchy underground tuber is highly digestible and can be eaten raw or cooked, as there are no toxins associated with the tuber.  Jicama can be eaten raw – sliced into sticks and used as a crudité, dipped into raw chilli powder then dipped in lime juice. It can also be used grated in salads mixed with tropical fruits and a handful of coriander leaves. The tuber can also be lightly cooked after peeling, slicing and dicing – it tends to retain its crispness when cooked and is often used in stir fries as a substitute for water chestnut.

The dried vines are very strong and can be woven into fishing nets.

Yam

Yam (red and white, five-fingered yam, greater yam, lesser yam, aerial yam)Yam (Web)

Dioscorea family

Origin: hot, humid tropical Pacific Islands

Plant: mid-Sept to mid-Oct

Harvest: When all foliage has died down. Dig gently around the yam taking care not to damage it (cuts will reduce storage life).

Yams can be stored for several months in a cool ventilated area. Depending on the variety, yams can be baked, eaten with dark green leafy vegetables, fish, meat, peanuts and milk, used in curries, fried in oil, used to make a purple cake as well as purple yam wine, made into a dough, flour and African fufu.

 

Winged Bean

By

Winged Bean (aka four-angled bean)

Winged Bean (Web)Psophocarpus tetragonolobus syn. Goa Bean

Origin: hot, humid tropical Madagascar and Asia

Plant: Sept – Oct – into pots initially

Harvest: April – May. Young 4-angled pods with wavy margins can be picked for eating at any stage. Do not disturb the lilac flowers, as they fall off quite easily. Allow some of the first beans to mature on the vine for seed saving. Tubers contain 20% protein and taste like early season potatoes. Can be eaten raw or cooked. Young pods, flowers, leaves, vine tips and mature seed are all edible. To improve germination, sandpaper seeds or soak in hot water until swollen.

Turmeric (Curcuma longa)

By

Hardy clumping perennial from the ginger family.

Other Names: Indian Saffron, Yellow Ginger

Origin: SE Asia, India

Size: 1m high, 1m spread

Growing conditions: full sun

Propagation: Replant rhizomes in spring after autumn harvest.

Growing tips: Dig rhizomes up when the tops have died down. Can be left in ground during winter dry season or lifted and stored in dry sawdust or sand.

Use: Like ginger and galangal, turmeric is a spice and can be added to any cooked vegetable dish. Grate turmeric with some onions and saute in hot oil. Raw, it has a pungent bite and can lift a salad. Used to colour rice and curry dishes and curry powder.  Makes a great ‘turmeric, galangal and chilli paste’.

Availability in shop: late spring to summer

Taro (Colocasia esculenta)

By

Clumping perennial with large tubers and green or purple stems. Note the cut in the leaves does not go through to the stem.

Other Names: Talo, Dalo, Dago

Origin: South-East Asia

Size: 1.5m high, 1.5m spread

Growing conditions: partial shade to full shade

Propagation: Separate pups from main plant.

Growing tips: Grows well in boggy or partially submerged conditions.

Use: Harvest in winter, when the leaves begin to look tatty. The corm is harvested 8-10 months after planting. Starchy corms are a good source of calcium and iron.  Wash the taro after harvesting and allow to dry.  Harvested taro corms can be stored in a dry airy place for 2 – 3 weeks at most. After this time they will rot.  Roast or cook whole to preserve nutrients. Poi is a lactic ferment made from boiled taro corms. The leaves can be picked 2-4 weeks after planting and take about 6 weeks to mature. They can be boiled, pulverised in a blender then added to soups, casseroles and stir-fries. They are traditionally used as food wraps and cooked in a mumu or cooking pit. Young leaves will take 5-10 minutes to cook while older ones 15-20 minutes before the oxalate crystals have been rendered neutral. Can be frozen.

Availability in shop: all year
