 Sandal wood is known for it therapeutic properties and is used in Ayurvedic medicines as much as it is used in religious rituals in India. Sandal wood is also used in Awadhi cuisine for Kebabs etc and is slowly making it way into a common man's kitchen in India in the form of ready made sandal wood syrups and sharbats. We tried to make our own for use in cocktails and non zero proof cocktail drinks and the wood can add wonderful aromatics and complexity to a simple drink. Here is our recipe.
