Fresh turmeric has a warm, spicy, earthy flavour that can be quite strong when you first try it. If you're new to fresh turmeric, add a few slices to your smoothie, blitz it then taste and see if you think it needs a little more. Any leftover turmeric will keep in your fridge for 1-2 weeks. It's good for grating into soups, stews, curries and even porridge. Be careful though, as it does like to stain things yellow. Wiping your board and knife with a cut lemon after you have slices or grated it will help keep them stain free.
