Here's how to do it:
Ingredients: 4-1/2 ounces Italian (sweet) vermouth, 9 ounces gin
Do this for 3 drinks: Gently pour the vermouth and gin into a glass pitcher. Stir (don’t shake). No ice for this one either. Just pour into cocktail glasses and serve at room temperature.
If you’re feeling fancy: Rub a piece of lemon peel may be rubbed around the edges and garnish with lemon wedge.
