Ok my findings
I put 200 ml of base in my pan , i have an electric hob so turned it up full blast , i heated up until bubbling for a few mins and kept scraping back , i then added 1 TBS of the taz spice mix and kept scraping back for another 2 mins , added another 100 ml of the base and kept reducing , i tried it and its got a lovely taste , tastes very like my takeaway below me, on the spice mix i never had the madras powder , so i used curry powder to sub this and only had methi seeds lol, i was experiment over next few days but i believe this is it, tastes same i only think the technique needs perfected
Thank you for this !!!
