5 Stars ! I used Bitter Lemon as my fizzy drink but you couldn't see though the iceblock at all, so once the limes pieces were arranged, I topped up the other side with water so that the visual effect wouldn't be lost. Although the fizzy drink was very shallow in the muffin pans, the frozen result appeared to be much thicker in size, so definiately be conservative when pouring it in. I think that the biggest surprise was simply how well the lime and bitter lemon flavours went together once they started to melt together .. and that's what earns this recipe 5 stars. Please see my rating system: 5 stars for a super easy make ahead recipe where you can have a stash of these iceblocks in the freezer and just make a dramatic looking drink in an instant when the guests arrive. I will be making this often. Thanks!
