Prepare the Blender: In a blender, add the fresh strawberries, white rum, lime juice, simple syrup, and ice. If you prefer a sweeter cocktail, you can increase the amount of simple syrup.
Blend: Blend the mixture until it becomes smooth and thick. If it's too thin, add more ice and blend again.
Serve: Pour the mixture into a chilled cocktail glass or daiquiri glass. You can garnish with a strawberry or a lime wedge on the rim, if desired.
Enjoy: Serve immediately and enjoy your homemade strawberry daiquiri!
