Ingredient Notes:Liquor- Not a vodka drinker? You can easily swap gin in its place. Cranberry juice cocktail - This sweetened cranberry juice is my go-to for most cocktails as it gives the best cranberry flavorOrange Liqueur- Cointreau is my favorite for this martini but you can easily use triple sec or Grand Marnier if you prefer.Simple Syrup is basically sugar water. You can certainly buy a bottle of it at the liquor store, but making simple syrup at home is super easy (and waaaaaay less expensive).Grapefruit Juice- Fresh is best but bottled will do in a pinch.
