2L sparkling water
1 packet of raspberries
3 tablespoons sugar
1. Cut all the lemons in half and using a jucier squeeze all the juice out & pour into a jug
2. Mash all the raspberries (leaving 4 or 5 for decoration afterwards if you wish) in a sieve above a saucepan, then add in the sugar and heat until slightly bubbling whilst constantly mixing then add to the lemon juice
3. Give it a good stir and then slowly add in the fizzy water (adding it too quickly will make it all bubble up!)
4. Have a quick taste & add more sugar if needed. If not pour gently into bottles and there you have it!
