First, prepare a syrup. For this, mix the sugar, water, and lemon dash in a pot. Heat and when it comes to a boil, lower the heat to a minimum. Cook for 8-10 minutes, set aside, and allow to cool.
Blend the syrup with the fruit.
Pour the liquid into a clean dish (glass or stainless steel) and freeze it.
Scratch the frozen mixture with a spoon and pour into individual glasses, forming a thin slushie that will dissolve in the mouth.
