Bobby,
i feel a very good choice of subject and a key factor in us achieving our desired result.
see recent post "LB's spice mix"
https://curry-recipes.co.uk/curry/index.php?topic=2444.new;topicseen#newsince joining the site i feel i am at last making good progress towards being able to put a decent curry on the table now and again as a supplement only to my long standing and unbreakable affinity to my local takeaway.
i have now made a few bases some many times (KD, LB, parker21, CRO development, ronnoc). i intend to make saffron next. what's clear to me is once you've achieved a set threshold for the base ie one of quality (which i list parker21 & ronnoc*) it's impact on the final dish is limited. i still have a few uncertainties such as addition of garam masala, turmeric and cooking time.
the other step improvement i feel i've gained (other than quality base) is the cooking technique ie frying & toffee/choking smell.
but this is very much dependent upon the spice mix. the LB mix on it's own gets very close to restaurant/takeaway taste. i am sure in the same way as for bases other spice mixes will deliver above the required threshold ie one of quality and again at this point it's impact on the final dish is again limited.
given the use of a quality base and quality spice mix i still find myself short of the desire takaway taste. this i now think may be where the curry powder comes in (ie CA's is very diverse in spices typ 15 off).
i intend to try equal proportions of spice mix & curry powder on my next go and hope this might deliver the depth of spice without any one spice overpowering that i am aiming for.
I feel we need to explore this topic much more.
*i thought the ronnoc base taste was very good and the bulk vegetables something i intend to bring into my cooking at some stage. i did find it difficult to get a depth of spice at the cooking stage but i am convinced this was down to my lack of experience with the base as opposed to a deficiency - i got a very good korma but i at heart i am not a korma fan.
