Make sure the lemons are washed thoroughly.
Quarter both lemons and place them in one of the containers.
Muddle the lemons until you’ve gotten as much juice as possible out of them.
Add the sugar to the container with the lemons and give it a little shake. The lemon juice helps dissolve the sugar.
Fill the container ¾ of the way with ice and then add the water.
Place the lid on, before making the hole in it, and shake it really well, combining all the ingredients thoroughly.
Make a hole in the lid using a 5/16” hole punch, or by your preferred method, add a straw, and enjoy your fair lemonade!
