Some fresh produce can be tricky to buy - especially when you can't see what's on the inside. Tai Seng Yee, executive director of Zenxin Agri-organic Food in Singapore, tells you how to get it right every time.
Look For: One that's small and heavy - it's fresher, juicier and has more layers.
Look For: A dry and papery skin that is intact and free of black patches. Check that the tops have not sprouted, which could point to old stock and moisture exposure.
Look For: A plump and voluptuous gourd with shallow grooves - signs that it is mature and at its most flavourful.
Look For: Bright and shiny skin, with no black spots. However, the only way to gauge the intensity of the flavour is to break off a knob and smell it.
5 Cauliflower and Broccoli
Look For: Tight, firm and fresh-smelling florets. Give it a sniff - there should be no hint of decaying odour.
6 Lady's Finger
Look For: Dark green ones with no brown or black patches. Choose small ones if you'll be steaming or stir-frying them - they are more tender, but more gooey. Larger ones are older and tougher, and are better for stews and curries.
7 Sweet Potatoes
Look For: Small ones, which are sweeter and have a more intense flavour. The skin should be free of coin-sized black marks, which may indicate that the tubers have been farmed in soil that's too wet (from too much rain) - the flesh is likely to turn black when cut.
Look For: Firm and green stalks, especially at the ends. As the tips are the first to turn bad, check that they are compact and not decayed.
Tip: Choose produce like melons, gourds and corn that are heavy for their size - lighter ones could have lost their moisture and may be less fresh.
