Utterly unbuttered!

As per Beatmaster's recommendation I will attempt this today.
There is no one way to make Butter Chicken and no right or wrong way. And while this should be reassuring to me, it has made it only harder. Whose recipe should I follow. With or without the khada masala. Shall i put the grated onions in the marinade or bhuno with the tomatoes.
I am of course, in the greater interest of all things related to the love of my life - going to do the
Low Cal version of, wait for it, Butter Chicken!!! Hahahahahahahaha.
I think I need a weighing scale for the kitchen as I am going nuts dividing all recipes by 4 or 5 or 8. (i am now only making bite size portions - too much wastage. And leftovers, well, you know what i thought about bringing my cooking to work! (See for opinion on leftovers)
