Lemonade is a drink made from lemon juice, water and sugar. Lemonade made commercially at a bottling plant is often carbonated, which means it is full of fizzy little bubbles. Home-made lemonade tastes nicest if you dissolve the sugar in water by making it into a syrup first. Make sugar syrup by heating 1 cup of sugar and 1 cup of water in a saucepan until all the sugar is dissolved. Add this to the juice of about 5 lemons (1 cup of juice) and then add 3 or 4 cups of cold water. Put the mix in the fridge until it is cold, and then serve with ice and lemon slices.
