This is probably a thread by itself to be honest - Turmeric
I use it all the time - its in the base, in powders, for marinating meat to give colour - its in our yellow rice.
There isn't an unpleasant taste mate - the rice is cooked with green cardamoms, cloves and cumin seeds and a level tsp. of turmeric in the water - the rice is a lovely yellow colour and has subtle flavours of the spices nothing harsh at all.
What are you doing with the roots?? have you tried drying them out completely then grinding into powder. If you grind the roots which aren't dried they have an oily stickiness to them which is a real pain to clean. I have used fresh roots for many other things out here in Thailand.
Phil turmeric has so many health benefits - which have been proven. Its great to have as an ingredient.
