Give your martini glass a sugar rim. Wipe the rim of the glass with lemon and dip it in the sugar.
Fill a cocktail shaker with ice. Add vodka, simple syrup, and fresh lemon juice. Cover and shake vigorously.
Strain the drink into the prepared glass. Garnish with a lemon twist and enjoy!
If you have extra lemons, you can zest them and combine the zest with the sugar to make lemon sugar for the rim of the glass.
To make the drink even colder, you can chill your martini glasses in the freezer beforehand.
Feel free to add more or less vodka to make the cocktail as strong as you prefer.
You will need to shake and not stir this cocktail. The lemon juice and vodka have different densities, so they need to be shaken to combine thoroughly with each other. The ingredients may separate if you stir the martini.
Don’t have a cocktail shaker? You can use a mason jar or any jar with a tight-fitting lid.
