I have tried Nutralite as well but it does not taste as good as Amul butter.
With amul butter, you can make any dish very very taste. If you dont have amul butter applied on pav(pav bhaji) then it is worthless. amul makes the pranthas, pav bhaji and almost very thing taste so well.
The only thing is that unlike Nutralite, this has got fat content. I wish Amul comes up with a version which has good good fats(omega 3 just like Nutralite)
