Dry and fresh turmeric aren't used interchangeably. And non-stale turmeric does have flavor, but it's a musty pungent one so needs a light hand.I use fresh turmeric in some of my Thai curries and Burmese curries. I use dry turmeric in almost all my Indian recipes. Indian cooking doesn't use fresh turmeric much. In India fresh turmeric is used as a home remedy antiseptic.
