Achieving balance, ideal dilution and a good chill are essential to the enjoyment of this spirituous sublime classic.
Pre-batched bottled version serves...
I like the old fashioned Old Fashioned! I have gone to using a tsp of light brown sugar and 1/2 ounce of water with 1/2 of triple sec too for an orangey sweetness.
I should mention too that I use 2 shots of Bourbon. I prefer that to Rye or a mix of Bourbon and Cognac or brandy. Use 6 to 9 dashes of Angostura bitters to wet the brown sugar.
I also like it slightly sweeter and use a touch more sugar than this. Agree dark sugar is the way to go.
And like you I appreciate an orange note.
I get it from using a mix of orange bitters with angostura bitters, but primarily from spraying an orange zest through a match flame onto the surface at the end. My children enjoy the fireball that makes, I enjoy the massive orange aroma notes this adds.
