I like to keep it simple when trying to determine the difference between sweet and savory. I know this is not a text book deffinition nor the way most look at it, but put simply if a dish is for dessert, a sweet breakfast item (i.e. french toast, waffles, etc.) or is just a traditionally sweet dish then it is "sweet". Anything for lunch, dinner, aps, salads, soups, etc. are "savory". Of course any of these dishes main contain one or more sweet elements (such as vanilla) but are traditionally not sweet items.
