Ok so I experimented this weekend and made several batches of Champagne marshmallows, and they came out wonderfully!! I used nightscotman's recipe as a base, but altered it a bunch! the champagne doesn't set as well as using all water, so i had to decrease the total amount of liquid in the recipe by a 1/2 cup. but i used Champagne in both parts of the recipe -- blooming the gelatin and making the sugar syrup. i also added some vanilla paste,to the second batch, which was a great compliment to the Champagne. finally, i used onyl 2 cups of sugar since Champagne already has a sweetness to it. YUM-O!! they definitely tasted like Champagne! sorry I don't have any photos to post, but they look just like regular white marshmallows since the color is not altered. although, i wonder if they would be pink with rose Champagne....now that's another experiment.
