2 oz. rye whiskey
1/2 oz. lemon juice
1/2 oz. orange juice
1/2 oz. blood orange juice
scant teaspoon grenadine (if using homemade grenadine, bump up to a 1/2 oz.)
dash of orange bitters
dash Angostura bitters
Shake all ingredients save for the Angostura bitters with crushed ice and pour, ice and all, into a double Old Fashioned glass. Add a dash of Angostura as a sort of float on top of the ice, and let it seep down.
You can also pour it as a cooler in the summertime...strain the cocktail into a Collins glass half full of crushed ice and top up with club soda or seltzer.
