Cranberry Jalapeño Margarita

Ingredients

Brush rim of glass with lime juice (you can brush with simple syrup if you want, but note it may be a bit spicy so only use if you love spiciness!) and place upside-down on a small plate of coarse salt or sugar to coat rim. Fill glass with ice.
In an ice-filled shaker, combine cranberry juice, tequila, simple syrup, and lime juice. Shake well and pour into prepared glass.
Garnish glass with cranberries and jalapeño slices.

Put water and cranberries in a large saucepan and bring to a boil. Lower to a simmer, add in spices, cover saucepan, and let cook for 20-25 minutes.
Strain mixture through a fine mesh strainer to extract liquid (Dispose of cranberry mash or save for another use).
Pour liquid back in saucepan over low heat and stir in sugar and lime juice.
Pour into heat-proof bowl or pitcher and place in fridge to let cool completely before using.

You should be able to make about 8 cocktails with cranberry juice )and single batch of jalapeño simple syrup).
For a big batch cocktail, you can mix this margarita in a pitcher: to serve 8, I recommend mixing: 4 cups cranberry juice (full batch), 3 cups tequila, 1 cup jalapeño simple syrup, and ¼ cup freshly squeezed lime juice.
If making this cranberry juice to drink as is, you may want to increase the sugar a bit. I purposely leave it a little tart since the margarita also has simple syrup in it.
