Smoked Old Fashioned
Serves 1
Ingredients:
· 1.5 Tbs. Simple Syrup
· ¼ cup whiskey, bourbon, or brandy, etc.
· ½ cup lemon lime soda mixer
· Dash of bitters
· 1 orange sliced
· 1 cherry
Instructions:
Preheat your Pellet Grill to 180F to batch of smoked simple syrup. While the grill pre-heats add 1 cups water to 1 cup sugar. Dissolve. Pour into your 12” Skillet (or sheet pan with at least 1-2-inch-high sides.) Place on the bottom rack for 2 hours. With heat guard gloves, remove from the pellet grill and cool completely. Bottle in an airtight container such as a mason jar and store in the refrigerator for up to a month.
Slice oranges and drain your cherries. Place your cherries on a small baking sheet on the top shelf of the grill. You can place the cut oranges direct on the bottom grate next to your Cast Iron Skillet. Smoke oranges and cherries for 10-30 minutes according to your smoke preference (10 minutes being for a little smoke and 30 minutes for a lot of smoke.)
Pour simple syrup mix to cover the bottom of your CamelBak Horizon Rocks Tumbler. Add ¼ cup of your alcohol of choice Stir. Add ice. Stir again. Add ½ cup of your favorite lemon lime soda mixer. Stir until foamed. Garnish with smoked orange and/or cherry.
For a mocktail use barley tea (steeped for 10+ minutes) instead of the whiskey. Bitters tend to have a very minute amount of alcohol in comparison to the actual drink. Keep it as is or purchase non-alcoholic bitters like Dram.
