Probably my fourth attempt, and I think that I can finally claim success on this occasion. MTR dosa mix with extra whole fenugreek seeds and salt, left to ferment for several hours rather than the five minutes stated but otherwise to spec., then thinned with just a little water and whisked immediately before cooking; MTR sambar mix, made about 1/2 as thick as recommended with added mustard seeds and softened curry leaves; simple potato and onion stuffing, with just a little carrot for colour, cooked with salt, turmeric, black mustard seeds, softened curry leaves and a little hing.
