Affinity Cocktail

I didn't expect much from this cocktail but it was amazingly good.
The 'Affinity Cocktail" an interesting mix of ingredients, and the orange flavor was there. This one is on our repeat list.

The recipe (page no.28 from Mr. Boston Bartender's Guide):

1 oz Dry Vermouth (Noilly Prat)
1 oz Sweet Vermouth (Noilly Prat)
1 oz Scotch (Dewar's White Label)
3 dashes Oranges Bitters

Stir with ice and strain into cocktail glass. I garnished with an orange slice.

Cheers!
