DIY Coffee Liqueur
DIY coffee liqueur tastes like like a fresh cup of coffee with added depth from rum and just enough sugar to make it great for sipping or mixing—or baking and dessert garnishing. The quick steeping time means no patience is required.

Turbinado sugar is also known as raw sugar, and is available at most grocery stores. You can substitute other types of sugar if desired.
