Instructions

Step 1: Prepare the Cold Brew

  1. In a large jar or pitcher, combine 1 cup coarsely ground coffee with 4 cups cold filtered water.
  2. Add a pinch of sea salt to enhance the coffee’s flavor.
  3. Stir gently until all grounds are fully saturated.
  4. Cover and let steep at room temperature for 12–24 hours.
  5. Strain through a cheesecloth or fine mesh sieve into a clean container. Store in the refrigerator for up to a week.

Step 2: Make the Toffee Syrup

  1. In a medium saucepan over medium heat, melt 1/2 cup unsalted butter.
  2. Add 1 cup brown sugar and stir constantly until the mixture is smooth and bubbling, about 2–3 minutes.
  3. Slowly pour in 1/2 cup heavy cream while whisking to combine. Be cautious, as the mixture will bubble up.
  4. Reduce heat to low and simmer for 3–4 minutes, stirring occasionally, until thickened.
  5. Remove from heat and stir in 1/4 tsp fine sea salt and 1 tsp vanilla extract.
  6. Let cool to room temperature, then transfer to a jar. Store in the refrigerator for up to 2 weeks.

Step 3: Assemble the Sea Salt Toffee Cold Brew

  1. Fill a glass with ice cubes.
  2. Pour 1/2 cup cold brew concentrate over the ice.
  3. Add 1/2 cup cold filtered water or milk (use milk for a creamier texture).
  4. Stir in 1–2 tbsp toffee syrup, adjusting sweetness to taste.
  5. Sprinkle a pinch of flaky sea salt on top for a salty contrast.
  6. Optional: Add a dollop of whipped cream for extra indulgence.
  7. Stir gently before sipping to blend the flavors.

Tips

  • For a stronger coffee flavor, use less water or milk when diluting the cold brew.
  • Warm the toffee syrup slightly if it thickens in the fridge for easier pouring.
  • Experiment with plant-based milk (e.g., oat or almond) for a dairy-free version.
  • Use high-quality flaky sea salt (like Maldon) for the garnish to elevate the drink.

Serving Size

Makes approximately 4 cups of cold brew concentrate, enough for 8 servings. Each serving uses about 1/2 cup concentrate.
