Notes
Notes: If you want it extra slushy, then use frozen strawberries! If you don’t want it slushy, just play with the ingredients, subbing water for the ice. Depending on the tartness of your lemons & the strawberries, you may need a bit more sugar. Once you've made the basic recipe above, sample & adjust as needed.
