Thomasm,
this base will give you a good idea on the method and the taste that's needed (
https://curry-recipes.co.uk/curry/index.php?topic=3462.0). i now use slow simmer throughout and keep lid on for 2nd stage. i use the same method for all bases that i make the others being rajver and saffron.
you can get very decent result on an electric hob with a good flat bottomed pan and a splash guard. you won't need the abrasiveness on a hob. the thinness of the base can be less too.
the starting point for the sauces and pastes is the Ashoka. it's something i still don't feel we have a definitive list of what BIR's use. my list includes garlic puree, g/g puree, bunjarra, red chilli sauce, green chili sauce, red masala sauce (combine as per Zaal inc the white for such as korma), nagga sauce, pathia, green chutney "hari". i tend to make a batch and store as ice cubes. best is fresh and aim for g or g/g along bunjarra to be fresh whenever poss. i also include boiled chopped onion, hot fried sliced onion/green pepper.
essential too - the tgad2007 chef garam (there is a Zaal version too) - i now use the powder form in place of the muslin bag or spice ball (

for mix powder there are quite a few goods ones although i've not tried loads (Derek Dansak, CA aka, Kushi, Bruce Edwards). i currently only use mouchak. i don't add "extra's" ie garlic powder, msg, cardamom seed etc. i only work on coriander:cumin seed of 2:1.
on a hob the technique is not as obvious as on a hot burner and this is worth a look (

as you get into things just post questions in the relevant areas.
given his current absence "CA" it's well worth mentioning that he is a star and has learnt me a great deal.
if you are technically minded i posted a base spreadsheet a while ago which might be of interest. the reason for mentioning CA is that i started on CR0 in his base development group and see this as essential grounding/starting point.
much in common, best wishes
