Step 1

Heat the sugar and the water in a saucepan until the sugar is completely dissolved.

Step 2

Remove the syrup from the heat, and stir in the vanilla extract and the lemon juice. Let the syrup cool and then store in the refrigerator.

Step 3

Mix 1 1/2 to 2 ounces of the syrup into 8 ounces of soda water. Or, you can make a big batch of cream soda at once, using the same ratio of syrup to soda water.
