The Boston Sour is a very sweet and silky sour owing to the large portion of sugar and egg white. It isn't a standout among many sours that include egg white, however. To make it more regionally specific, I picked an Irish whiskey, Donegal Estates, which is a good blended whiskey for mixing. With all the Irish-American influence in Boston, it seems like a good choice.
- 2 oz. blended whiskey (Donegal Estates used)
- 1 tsp. sugar
- 1 oz. lemon juice
- 1 egg white
- lemon wheel
- maraschino cherry (green for St. Patrick's Day used)
