Cola Syrup - Cooking like a Boss

A really nice, quite floral cola. Dilute with cold sparkling water like a cordial. Make sure all ingredients are food grade and all oils are pure. Kola nut extract is sold as a tincture. The caramel is commonly sold as brewer's caramel. The concentrate can be stored in a cool dark place for extended periods, as can syrup. Each batch of syrup is about 1.8l and makes about 14l cola. Concentrate makes about 90l total. You might want to open the door while mixing the oils. They're potent. Also, be careful handling ingredients. Some are irritants and others stain. Micro-pipettes make measuring much easier. Adapted slightly from this recipe https://www.youtube.com/watch?v=KWaNiwcQK2M

Flavour Emulsion

This step makes an emulsion out of the oils so they'll mix with the ingredients in later steps.

Concentrate

The concentrate mixes in the remaining flavourings/colouring but leaves out the sugar (and some water) so it takes up less space in storage.
