What a find! At the Murwillumbah Farmers Market one of the organic farmers grows garlic.... so there are garlic flowers available for sale too. If you come across some, grab them.
You can use the flower buds raw: Break open the bud and sprinkle the flowers on your salad or evening steamed greens. Slice up the stems and add them to your rissole mix. They'll provide a sharp garlic edge of flavour.
