Step 1

Coarsely chop the cranberries and place in a medium saucepan with water. Simmer the cranberries for 20 minutes.

Step 2

Gently mash the cranberries and strain through cheesecloth or a fine strainer (you should have about 1 cup of juice, add more water if not).

Step 3

Place the juice back in the saucepan with 1 cup of sugar. Bring to a boil and immediately remove from heat. Set aside to cool.

Step 4

Fill a shaker halfway with large chunks of ice. Add in 2 oz (1/4 cup) of each the cranberry simple syrup, lemon juice, and vodka.

Step 5

Shake until mixed and chilled well, and pour into a martini glass. Enjoy immediately!
