RE: desserts with no milk
Do yourself a google search for Kosher desserts. When meat is on the menu, there can be no dairy in the entire meal, including dessert. This is the reason that I NEVER leave room for dessert at a kosher wedding! The desserts are always sub-par because of the dairy restriction.
An interesting side-story is the history of Robert Rich, the inventor of non-dairy creamer, which is present in practically every Kosher kitchen on earth. Robert Rich passed away earlier this year, leaving behind a net worth of $2.5 billion.
