The pre-cooked chicken is made using a simplified CA recipe -
http://www.curry-recipes.co.uk/curry/index.php/topic,1555.0.htmlI say simplified because I don't bother with the Coriander (sounds strange!). This recipe gives me perfect results using chicke thighs, which I much prefer as a meat anyway. Sometimes for quickness I use chicken breast like yesterday. If I use chicken breasts I only ever make enough for the evening (never freeze it). I don't know why I decided to freeze it this time, (oh yes, missus is on a diet...again).
I've been having good results adding raw chicken straight to the the sauce when cooking recipes such as Madras and not bothering browning it, exactly like when making Thai style curries.
