the thing that got a smile from me was the comment, "it's not about secret ingredients or difficult technique."
as for if it would work for curry i'm not really not sure. i see big differences between the 2 techniques.
a thought to quench the appetite a little is that i've recently been banned by my good lady from cooking in the kitchen.
i do like to try out a few variations and doing this in the kitchen makes life so easy. to get a closer taste i started heating a balti dish (~300C)(a bit like the nottingham garlic tarka) and then pouring the cooked dish (cooked slowboat) into the heated balti dish and letting it fry away without stirring for a few minutes.
it does get a decent result but the flames and flim of oil in the kitchen were apparently too much.
the fresh coriander i found also needs cutting very fine as it has a tendency to burn easily and spoil the effect.
