Asian basil. Asian basil is slightly coarser than the sweet basil of Europe, and with a more robust aroma. It survives cooking in stews, adding a fresh menthol, camphor end of the spectrum.
Snake gourds are bright green, thin-skinned gourds which can grow as long as 2 meters (6 ft). Since they have a tendency to curl they can frequently be seen with rocks tied to them to keep them straight. They should be rubbed with salt to remove the downy surface of the skin and can then be cut open, the central core of seeds removed and then cubed or sliced for adding to stews and rasams. They do not have a great deal of flavour.
Pomelo. A citrus fruit similar in appearance to a grapefruit with one slightly pointed end. Once the thick skin is peeled, the segments need to have the tough leathery coating pulled away. Inside, the flesh can be deliciously sweet and juicy. It is better left for a few days after picking before it is eaten. There are pink and white versions. Is sometimes used in salads and savoury dishes.
