Procedure
- In a medium size pot, combine sugar, water and strips of orange zest. Bring to a boil, stirring to dissolve sugar.
- Reduce heat to medium-low and simmer for 3 minutes.
- Turn off heat, cover, and allow mixture to infuse and cool to room temperature; 15 minutes. Place cooled syrup into the fridge to chill completely.
- Place the ground coffee into a large bowl. Gradually add the cold, filtered water and slowly stir to ensure all grinds are moistened. Cover and place into the fridge to steep; for at least 12 hours.
- Strain the orange syrup through a fine-meshed sieve placed over a measuring cup. Discard solids.
- Line the same fine-meshed sieve with a coffee filter and place over a pitcher.
- Pour the cold brew coffee concentrate over the lined sieve. Allow the coffee to slowly drip through the sieve. Discard solids.
Stir in 1 cup of the orange syrup into the cold brew concentrate.
