Buy dried lemon myrtle leaves whole or ground from a reputable retailer. To get fresh leaves it would probably be necessary to purchase a tree from a native nursery and put it in your garden.
Store whole and ground leaves in airtight containers away from light and heat. Whole leaves will last for up to three years, ground for at least 18 months.
Tips & Tricks:
Use in stir-fries and Asian curries as a lemongrass substitute. Add towards the end of cooking, no more than 10 minutes before serving, as long cooking destroys the delicate lemon notes. Use sparingly, or a camphor-like eucalyptus taste will override the lemon.
