Make the ice cubes. Divide the strips of lime and chunks of strawberry among an ice cub mold or I used a mini muffin tin. Mix the lime juice with the tequila and pour over the the fruit or just pour the lime juice over the fruit if you are not using the tequila. Freeze at least one hour before serving.

When your ice cubes are ready, make the Strawberry Basil Limeade. Blend the strawberries, lime juice and basil in a blender or food processor until smooth. If desired strain the strawberry puree through a sieve or fine mesh colander. I recommend doing this only if you have kids who will be drinking these, otherwise I would just leave the strawberry seeds in the drink.

Pour the strawberry, basil and lime mixture into a large pitcher. Add the sugar and stir to dissolve. When you are ready to drink the limeade, carefully add the sparkling water (or use regular water if you need the drink to sit a while).

Check the flavor and adjust according to taste with more sugar if needed. Serve with the tequila lime ice, or just the sour lime ice, and fresh lime and strawberries.
