1 part of Vodka
1 part of Grenadine
1 part of Tia Maria (or coffee liqueur)
4 part of milk
Add ingredients to a shaker over ice. Stir, pour, drink.
This is effectively an alcoholic milkshake. As you drink it, you see what each ingredient adds to the overall character; the vodka strength, Tia Maria for the coffee pick-me-up, grenadine for the sweetness and the milk to soften the finish.
