Ingredients

• 2 oz bourbon or rye whiskey (choose your favorite brand)
• 1/2 oz demerara syrup (see notes below for homemade recipe)
• 2-3 dashes Angostura bitters
• Orange peel (for garnish)
• Ice cubes (preferably large, clear cubes)
• Optional: Maraschino cherry for garnish

Equipment

• Old Fashioned glass (also known as a rocks glass or lowball)
• Bar spoon or stirring spoon
• Jigger or measuring tool
• Bar knife or vegetable peeler (for peeling orange zest)
• Small saucepan (if making homemade demerara syrup)
• Mixing glass (optional, for stirring)

Instructions

1. Prepare the demerara syrup if you don’t have it ready. Combine equal parts demerara sugar and water in a small saucepan. Heat gently, stirring until sugar dissolves completely. Let cool before use. Store leftovers in a sealed container in the fridge for up to two weeks.
2. Add the demerara syrup and bitters to your Old Fashioned glass. Use about 1/2 oz of syrup to start—feel free to adjust to taste.
3. Pour in 2 oz of your chosen bourbon or rye whiskey.
4. Add a large ice cube or several smaller cubes to the glass. The goal is to chill the drink without watering it down too fast.
5. Stir gently with a bar spoon for about 20-30 seconds, allowing the syrup and bitters to meld with the whiskey and chill evenly.
6. Express the orange peel oils over the glass by holding the peel skin side down and giving it a firm twist. Rub the peel around the rim of the glass to add aromatic oils.
7. Garnish with the orange peel and, if desired, a maraschino cherry.
8. Enjoy your perfectly balanced Old Fashioned with demerara syrup!

Tips & Variations

Pro tip: Use a large, clear ice cube to slow melting and maintain flavor integrity.

Customize your bitters: While Angostura is classic, try orange bitters or Peychaud’s bitters for a different flavor profile.

Try different whiskeys: Rye whiskey offers a spicier, drier finish, while bourbon tends to be sweeter and fuller-bodied.

Make it smoky: Add a splash of smoky Scotch whisky for a unique twist called the “Smoky Old Fashioned.”

Swap garnishes: Use a lemon twist or fresh rosemary sprig for a fresh herbal note.
