Ingredients:
- ½ cup Filtered water (for syrup)
- ½ cup (packed) Light Brown Sugar (for syrup)
- 1 large (approx. 3 in) Cinnamon Stick (for syrup)
- 2 fl oz Freshly Pulled Espresso (Double shot, medium-dark roast)
- 2–3 Tbsp Brown Sugar Syrup (chilled)
- 1 cup Ice Cubes
- 4–6 fl oz Oat Milk (Barista-style recommended)
- A small pinch Ground Cinnamon (for garnish)
Instructions:
- Phase 1: Creating the Brown Sugar Syrup. In a small saucepan, combine the water and the packed brown sugar. Add the whole cinnamon stick.
- Place the saucepan over medium heat. Stir constantly until the sugar is completely dissolved and the mixture just reaches a simmer. Do not boil vigorously.
- Remove the pan from the heat immediately. Allow the cinnamon stick to steep in the syrup for 15–20 minutes to infuse the flavour.
- Remove and discard the cinnamon stick. Pour the syrup into a clean jar, seal, and let it cool to room temperature before chilling thoroughly in the refrigerator (approx. 30 minutes). This cold syrup is crucial for chilling the espresso quickly.
- Phase 2: Assembling the Shaken Espresso. Prepare a fresh, hot double shot (approx. 2 fl oz / 60 ml) of espresso directly into a small heatproof vessel.
- Transfer the hot espresso to the cocktail shaker. Immediately add 2 to 3 tablespoons of the chilled Brown Sugar Syrup (adjusting for sweetness).
- Fill the shaker approximately three-quarters full with fresh ice cubes. Note: Using enough ice is essential for proper aeration.
- Secure the lid tightly. Shake the mixture vigorously and continuously for 15–20 seconds until a thick, foamy head (micro-foam) forms. The outside of the shaker should feel intensely cold.
- Fill your serving glass with fresh ice. Pour the entire contents of the shaker (the highly-aerated, foamy espresso mix) into the glass.
- Gently pour the 4–6 fl oz of chilled oat milk over the espresso mixture. Dust lightly with a pinch of ground cinnamon for garnish, and serve immediately.
