What to do with the whole turmeric rhizome
If you buy a whole turmeric in the shops, choose one that is still firm and with a skin that is not too wrinkled. Once purchased, keep it in an airtight container until ready for use – this way it will last for quite a long time (up to 2 months).
Fresh turmeric can be grated into salad, soups, stews and casseroles. Many people remove the skin, but it is not necessary if you want to add texture to your dishes. It is by no means harmful but do scrub well before using.
