I'm delighted how fizzy and true to the champagne flavor this recipe is! I used Island Pineapple Jell-O and pineapple juice. It turned out great! The mix was a little too bubbly after adding the champagne so I scooped the froth off before pouring in to molds. I think it would have been fine to pour even without de-frothing.
These were very interesting! They had a strange texture from the bubbly, but not strange enough to ruin the taste! I put them in dixie cups rather than make shapes. Made with lime jello and white grape juice. I am excited to try them again with other flavors!
