Cocktail made with vodka cranberry cointreau?

That sounds delicious! You're likely describing a variation of the classic Cosmopolitan cocktail, which is usually made with vodka, cranberry juice, Cointreau (or another orange liqueur), and lime juice.

Here's a basic recipe:

Cosmopolitan

* 1 1/2 oz vodka

* 1 oz cranberry juice

* 1/2 oz Cointreau

* 1/4 oz fresh lime juice

Instructions:

1. Combine all ingredients in a cocktail shaker filled with ice.

2. Shake vigorously until chilled.

3. Strain into a chilled martini glass.

4. Garnish with a lime twist or a cranberry.

Tips:

* You can adjust the sweetness by adding a little more or less cranberry juice.

* For a sweeter drink, try substituting triple sec for Cointreau.

* To make it tart, use a little more lime juice.

* A sugar rim on the martini glass is a popular addition.

Enjoy your delicious cocktail!
