Can I substitute powdered turmeric with fresh turmeric, and does anyone have any recipes using fresh turmeric?

Yes you can. You have to grind it or grate very finely. Grinding is better, releases more flavour and colour. You can eat fresh turmeric like ginger. Grate cosrsely, wlong with ginger, in equal parts and soak in lime juice, salt and pepper for a day or two. You can add some chopped chillies as well. It is tasty.
