Manhattan: 1 1/2 oz. Bourbon (I recommend Maker's Mark)
1/4 oz. Sweet Vermouth or Dry Vermouth
a dash Angostura Bitters (optional)
Garnish - Maraschino Cherry
On the rocks - just pour all ingredients over ice in a glass, stir and enjoy. Use equal measures of sweet and dry vermouth, with a lemon garnish for variety.
