Fill any glass just under a quarter full with crushed ice.
Then fill approx. 2/4 of the glass with passion fruit juice and approx. 1/4 with pineapple juice. Now squeeze one or half (the more, the sour) lemon and pour the juice into the glass. Then add a small spoonful of sugar and then fill the glass with cold water. Finally, add a little grenadine so that the ground turns red. Then stir everything well and the BBice is alcohol-free.
