What is the orange coloured cream inside McAloo Tikki called and what are its ingredients?

Question

From: http://www.mcdonaldsindia.com/happy-meals-menu.html

I have seen the onions, tomatoes, Aloo Tikki, and an orange coloured cream inside this burger.
I wish to know what is that cream called and what are its ingredients?

Answer 1

I cannot speak to its accuracy as I have no experience with this item or McDonald's at all outside the US, but Time In Kitchen in their recipe for a homemade version indicates:

For sauce, beat hung curd in bowl and add pinch of salt and tomato ketchup and mix well to smoothen it in order to avoid any lumps and keep it aside

Then again, according to SipputySup, it is "basically Thousand Island dressing)".

This question itself now appears on the 2nd page of google results when searching for "Aloo Tikki sauce" :-)
