chinois,
the waste reference was to what i was after from the bottle - just plain green chilli. i very much agree mint is essential in tikka and it's just recently dawned on me that i don't use enough (there's far more in it than u'd think).
have made the green chilli sauce "ashoka" in the past. i'm still undecided on whether the paste is worth the hassle c/w just adding the green chillies direct. i have a bottle of the pukka green chilli paste in the fridge to use on the next base. i also have the whole green chillies frozen too ready for a side by side comparison.
on the freezing i suppose i've just become too much at home with the principle - the practicalities of having stuff in a plastic bag in the freezer in "ice cube" lumps just seems to work real well for me - currently have yogurt, g/g paste, red chilli paste, bunjarra, garlic paste. i generally try to make fresh for w/ends and use the frozen for mid week.
