Having watched Dip's videos, I definitely think his cooking times are shorter than what they should be. I've been in a couple of BIR kitchens and these bases cook over night, so in my mind the longer you can cook them for the better IMO. I think Dips maybe trying to squeeze too much into a short time frame. If you follow his cooking times to the letter, you may well end up with some fowl tasting curries.
Anyway, i cooked his base last night, cooked the veg for an hour, then added toms and spice, and cooked for another hour. I then blended the base and packed it into tubs to put into the freezer. The outcome was pretty similar to the video posted by string? in this thread.
Looking forward to trying out Dips madras using this base.
