Hi Mike
If it's any help I use KTC Butter Ghee because I love the taste of butter and IMO KTC is the only one that tastes like butter. I just use it towards the end to achieve a really nice flavour and to get a good glossy look.
Some years ago I purchased 5 or 6 tins of Ghee, all different, lined them up on kitchen side, opened them up, smelt each one and then tasted each one and finally heated them up and tried them all again just in case there is any change etc but there wasn't and KTC WON HANDS DOWN.
That experiment cost me
