Ok, just had another attempt.
Followed the Balti recipie, but omitted the pataks, used a heaped teaspoon of curry blend instead (equal parts paprika, turmeric, Rajah curry power, cumin and coriander). Blown away! That meal *had* the taste, no doubt about it. If I were a resturanter, I spose I;d be selling it as a Bhuna. To recap then:
Heat 4 tablespoons of oil in yuor pan. Squirt in a teaspoon or so of garlic puree, spread and stir. After 20 secs, add in a ladle of pre fried, finely chopped onions, and a lug of blended tomatoes. Fry for 30 seconds. Add a ladle of Dhillon base, 1/2 teaspoon of salt, heaped teaspoon of spice mix, heaped teaspoon of dried fenugreek leaves, 1/2 a teaspoon of sugar, and a teaspoon of chilli powder. Also, half a chopped tomato, and I also put in a choopped green chilli. Mixed it all round, then added the meat and aladle of pre fried onion and green pepper chunks. Fried for 30 sseconds or so, then added a good handful of chopped coriander. 20 seconds later I added two further ladles of Dhillon base, and simmered for a few more minutes. Added a another generous pinch of coriander, stirred through, transferred to servinf dish. sprinked with more coriander.
It was magic. It felt like every ingredient was doing a job, and contributing to the flavour.
The pre fried onions are obviously important, as they lend a natural sweetness other wise missing. The fenugreek adds body in a subtle way - the kind of thing that you notice in its absence. The stregnth of spicing was spot on, and the heat was just right for a medium dish.
It looked fantastic, and smelt great too.
One thing I advise is to use a nice looking Balti serving dish, and to leave it a few minutes after cooking, to allow it to cool a bit - when it is piping hot, you can taste as much.
As you can probably tell, I'm rather excited. Big thanks to MarkJ for posting his observations! For the first time ever, I got 'the taste'. Now I need to be able to repeat it.
