Wash the lemons and submerge in boiling water (I wish I could explain the benefits of the boiling water, but I’m just following directions)

Use a vegetable peeler to remove the zest from the lemons, add to a large jar or divide among multiple jars

Add vodka and sugar (to taste), and top with a lid

Shake or swirl the mixture occasionally over the next couple of days, until the sugar dissolves

Remove the lemon zest after 24 to 48 hours

Refrigerate and serve chilled
