What is this technique where they add a thick sauce and spread it out with
the back of a spoon

I'm sorry my question is so vague but I'm trying to research a technique
but have no idea how to describe it.
If you review the picture below, you can see the orange/yellow splodge! :)
I see this technique being used quite a lot but have no idea what it is
called.

Does this have a name or technique associated with it? If not, can some
one give an example of how to get this type of consistency. I want to
recreate this so the meal looks flash but have no idea!
