JerryM ,
I ended up using a RAJVER recipe for my base which used almost the exact ingredients as the T/A ,but I did leave out the Tom Puree and the 1 Tbs of Chili Powder.I wanted to try to end up with the same colour base as the T/A ( yellowy/green )and a sorta bland taste . I am beginning to think it's easy to overdo the Spices ( and especially Garlic )if it goes into the base and the Curry
I made the base this afternoon and to be honest when it all boiled down it didn't look to appetizing
but when I blended it all together it looked just like what I remember the T/A looked like and the taste was very similar too ,just like a very very weak Curry Sauce with the flavour of Onions and Coriander ( very mild )and just a couple of seconds of the 2 Green Chilies that went in.I'll get back to you tomorrow night when I make my Curry with the results :
