Wash and trim the strawberries. Place them in a food processor and pulse until they are rough chopped, then scrape down the sides of the machine. Puree until completely smooth. Let the machine run for a minute or longer to insure a nice smooth puree.

Push the mixture through a mesh strainer, using the back of a large spoon to make sure as much of it gets through as possible. Most all of it should go through, leaving just the small seeds behind. You should have approximately a cup and a half of puree.

To make soda, use 2 tablespoons of the puree for each 8 ounces of carbonated water. Mix and then serve immediately. You can adjust the amount of puree for a lighter or stronger flavor.

The fruit puree will keep in a sealed jar in the refrigerator for a week.

If you like you can add a squeeze of fresh lemon juice to perk up the flavor of any fruit soda, and conversely, if you find your soda is too tart, add a touch of honey.
