Hi - glad you enjoyed the recipes. Funny enough I had just bought the Kris Dillon book myself about 2 weeks before I stumbled upon this forum. Now after cooking about 35 curries based on recipes from this forum I now look at the KD recipes and can imagine what they might taste like. The KD recipes don't look right to me at all with a lot of flavour coming from garam masalla. I'm sure many of us on this forum have destroyed a curry by using too much GM in the past, usually following a poor recipe.
Regarding the oil, I did some calculations and if you made a single portion chicken madras using the SNS 2008 base and the madras recipe to match you would consume:
20 ml oil from the 250 ml base and 30 ml oil from the final stage cooking assuming 2 and not 3 tablespoons of oil. This makes 50 ml of oil which will weigh in at 46 grams. In calory terms this will add up to approx 396 calories per portion just from the oil. This doesn't worry me a bit as I normally eat a chicken curry with chappatis or boiled rice which don't add any more fat and I don't generally follow it up with a desert.
You could probably remove about a tablespoon of oil after cooking if you allow the dish to settle for a while without ruining the taste and then you would drop the oil content by 13.8 grams or nearly 120 calories.
I think if you reduce the cooking amount of oil you may get into difficulties when you add the spice mix as the mixture may then become too dry to work with in the pan.
Fat can be bad for 2 reasons - 1) Effects on cardiovascular system 2) sheer amount of calories.
1 is down to what oil you consume and 2 is down to your whole eating regime.
After doing some research into edible oils I now do the following:
I use rice bran oil for making my bases - It is said to be as healthy as quality olive oil. Secondly I do the final stage curries using 100% organic coconut oil - this stuff costs 26 pence a tablespoon but it works for me and the wife.
Sorry for the long post - if you are interested google for the health benefits of virgin coconut oil - it has unique properties despite the 93% saturated fat content.
