Start by putting the 300g pack of frozen raspberries in your freezer, and keep it there until the berries are completely hard and frozen.
Once the berries become hard and firm, take the pack of raspberries out of the freezer. Line up your ten serving glasses (use any type of bar glass you prefer), and equally distribute the frozen raspberries among these glasses.
Next, add a small amount of caster sugar to each glass, and use a fork to crush the berries lightly. You don’t want to grind them into a puree – instead, simply bruise and slightly flatten all the berries, to release their juices.
Pour the pomegranate juice into the glasses over the sugar and the crushed berries – make sure you pour this so that there is an equal amount of juice in each glass. Wait a few seconds, to allow the flavours to seep into each other, and then stir with a spoon, until all the sugar is dissolved. Do not allow any undissolved sugar granules to remain, as these will become unpleasant, crunchy grains in the otherwise smooth and clear beverage.
Finally, top each glass with a generous amount of chilled sparkling wine, and garnish each glass with lime wedges. Your pomegranate & berry sparkling is now ready – serve chilled, with a side of fresh raspberries.
