Cane syrup is a sweetener made from sugarcane. The name covers two different products: a thick dark syrup boiled down from pressed juice, and a clear bar syrup of cane sugar and water.
It sweetens and adds a little body, stirred or shaken. Its cane note suits rum best, and it is the traditional sweetener of the Ti Punch.
Plain 2:1 sugar syrup
Rich syrup works one for one. Bar cane syrup is about 72% sugar against about 67% for 2:1, so the drink ends up a touch less sweet.
Demerara syrup
Made 2:1, it adds a little brown-sugar warmth.
Dark cane syrup
Boiled down from juice, it tastes of molasses. Use it only where that heavy flavor suits the drink.
Molasses
No substitute for syrup. It is thicker and more bitter.
Unopened it is stable at room temperature. Once opened, refrigerate it, or mold eventually takes hold. Cold, it keeps a couple of months.
