urs53...From what I gather, sauces etc. can be used
as a garnish, see

Sour cream served as a dollop in the centre of Borsct is a garnish but wouldn't be
considered as such if it was mixed up as part of the soup.
In the same way, a drizzle of melted chocolate over a scoop of vanilla ice cream is a garnish,
and is a strawberry placed on top of that.
To me garnishes can take minimal effort,
but really elevate a dish from boring, everyday
fare.
