How do you make a Negroni?
Here is how to make a Negroni cocktail:

Ingredients:
- Gin
- Campari
- Sweet Vermouth
- Orange peel
- Ice for mixing
- Ice for serving; Single large ice "rock" generally preferred

Bar tools needed:
- Mixing glass
- Mixing spoon
- Strainer
- Glass for serving; preferably a cocktail tumbler style glass

Making the cocktail

- Place the ice (or ice rock) in the serving glass
- Pour 1 ounce each of the gin, Campari, and vermouth into the mixing glass
- Add 5-10 ice cubes to the mixing glass
- Using the mixing spoon, stir the ingredients vigorously for 20-30 seconds
- Using the strainer, pour the cocktail into the serving glass
- Twist the orange peel to release oil and aroma; rub orange peel around rim of glass; place orange peel into the cocktail
- Enjoy!

If you enjoy the negroni, you can experiment with the ingredients.  Many enjoy mezcal as a replacement for the gin.  Also, you can swap out Campari for other bitter style aperitifs; St. George's Bruto Americano is a good example of a possible substitute.
