We made this smooth treat when we had 1 orange in the refrigerator, & didn't exactly want to eat it before it went bad.
The first step we took was to make orange simple syrup.
Start boiling a small pot of water. Small, like 12oz-ish.
Peel the orange
Put the orange peels in the boiling water
Add 1 cup of sugar to the boiling water
Leave the orange peels, & sugar, in the boiling water for 5 minutes
After 5 minutes, let the boiling water, orange peels, & sugar cool off. Once it all cools, you'll have your sweet, orange simple syrup
Get a glass, we used a 12oz glass for a single serving, fill it 1/2 way full with our cold brew coffee, & as much ice as you prefer
Add a splash of chai tea to the cold brew
Pour your orange simple syrup over the cold brew
Don't forget about the actual orange, there's no need to waste it. You can slice it up, & garnish your glass with it. If you want drop some orange slices in your drink, that extra citrus-y-ness might balance the sweetness of the orange simple syrup. Or, you know, you can just eat the orange, oranges are very tasty.
