Triple Sec

The Triple Sec name refers to the process of distillation. Sec in French means dry or distilled and triple refers to the triple distillation process.

It's been a popular liqueur for more than 150 years, the Dutch East India Company created orange liqueurs by steeping orange peels in alcohol from the island of Curaçao and called it Curaçao liquor, and unlike Triple Sec, the Dutch added spices and herbs to the orange and Curaçao comes in a variety of colours such as clear, orange or blue. Blue Curaçao being the most used of them, in cocktails. Triple Sec is made from neutral spirits and the Orange peel used is harvested from oranges that have the skin still green, so that the essential oils are still in the skin and has not been absorbed into the flesh. This gives Triple Sec the intense flavour.

Vanilla Sugar is the regular granulated sugar infused with vanilla flavour, by using vanilla pods and seeds to flavour the sugar.
