How to make curry always come out dry\easily remove extra water?
I always just let the curry simmer in a pot with the lid off to let the water evaporate more so I have thicker curries. The other option (and this is what my Indian family does) is to pour the liquid (so leave out the potatoes, chicken, whatever..) into a smaller pan and bring it to a rolling boil for a while to reduce the gravy and let it thicken. Finally, add in the rest of the ingredients when it is as thick as you want it.
