This lemonade is easy to make both at home and outdoors!
First of all, pour 1-2 tsp of sugar on the bottom of the glass (or more, it all depends on your taste preferences).
After that, fill the glass with ice (if you have a thermos bag, then I think there will be no problems with ice at the picnic).
Then squeeze the juice out of half a lemon, we will need about 2 tablespoons.
Pour mineral sparkling water with ice, lemon juice and sugar into a glass, add a sprig of mint and you can enjoy!
