Add strawberries, light rum, lime juice and orange extract to a blender and blend until smooth.

Test for sweetness - depending on the strawberries and your personal taste, you might find that it is sweet enough for you.

If you prefer things a little sweeter, add some syrup. If your drink is sweet enough already, you might like to add a little water to thin it out and make it into a longer drink.

If you prefer to remove the strawberry pips, push the mixture through a fine mesh sieve.

Pour over ice and serve with a garnish of strawberry and lime.
