What is the fine-grained topic of the following text: I've been introduced to this by a friend and have noticed what a massive difference it makes, just one sprinkle on boiled/steamed veg, in soups, in meat, practically everything can have just a sprinkle, even less than salt and it really makes the flavours come out. Only return the topic.
Using a sprinkle of a certain ingredient to enhance the flavor of food.
