Papaya. There is great discussion about the difference between papaya and paw paw or papaw. Essentially, they are all the same thing. It just depends where you are. The size of a large avocado, it has soft-textured, fragrant, apricot-coloured flesh with small black seeds which must be stripped out. It is a great breakfast fruit. If you have an unripe papaya which you wish to ripen overnight, pierce it with a sharp knife several times. It should be cut lengthways as this facilitates the removal of the seeds.
Fish sauce. It is similar to nam pla, and made from fermented fish from which the liquid is cured and bottled. It is what we call fish sauce, and is used widely in Asian cooking.
