Yes, he definately says "butter", thought it looks a little pale to me (and is maybe a little too expensive to use)?
I'd be really interested to know what that pale coloured "vindaloo sauce" was! And also that "garlic pepper a little bit"!

What dish has butter, fresh chillis, chilli powder, fresh tomatoes, "vindaloo sauce", cream and coconut powder in it? Topped with coriander and slices of lime? A vindaloo strength Butter King Prawn Bhoona something or other?

....looked very nice though!
