Secret Santa,
I have seen this site before - as u say real good stuff. I recall a post on CTM a while ago.
on the technique i've had to adapt to slightly different - i put tom puree, spice, and a little base (1 chef) in all at one go. this way i can consistently cook the spice without burning.
i add the main base after around 1:30 mins which is about the same.
the video on the chicken vindaloo is also good to watch as the ingredients are slightly different (mix powder used).
i must admit i've never used quite as much bunjarra (~1 heaped tbsp) whilst they seem to use at least 2 tbsp and probably nearer 3 tbsp. i will need to give this a try and also to add straight after the g/g paste (as opposed to after the base).
