I've always used same amount of mix for any dish. over time settled on 0.5 tsp per portion having used max 2 tsp.
The 0.5 tsp comes from perception of BIR (rsubtle spice with individual dish ingredients the differentiator)
Chewytikka red CTM got me questioning QTY. I've made this a lot for family who wanted a copy of what they get from 2 local restaurants.
In short started off with no mix, then 0.5 tsp and fixed at 1 tsp. This only came about by making the dish a lot of times and the 'customer' input.
The question then is the QTY dish dependent and is there a rule of thumb. Typ
1) plain cream - high
2) plain curry - medium
3) complex - low
If Anyones got a better naming of the categories would appreciate as it would make the info more easier to apply/understand
