What is Prepared raspberry beverage?
I have a recipe that looks delicious for raspberry Bavarian cake. It doesn't seem overly difficult but the ingredients call for prepared raspberry beverage with no indication of what it actually is (all I know is I have to add gelatin to it). Any ideas? Is it juice? Alcohol? Syrup? The book calls for juice and syrup and liqueur in other recipes so I'm just confused on the terms.
