Always have a problem when making curry?

If it's too watery, take out the meat and boil it off until you have the right consistency, then add the meat back. If it's too dry just add a little boiling water to moisten it up a bit. Another way you could thicken it is to mix 1 tbsp of cornflour/cornstarch with 1tbsp of cold water in a cup then add this paste to your curry. Bring your curry to the boil for 1 minute and it will thicken up nicely. Good luck!
