No health food store in your area? You can buy syrup online from health food sites.
Alternatively, you can use brown rice syrup solids, easily found at any homebrew store or online homebrew store, but their gluten content may differ, which wouldn't be good for people who have to have a complete restricion, rather than an intolerance where they can withstand a tiny (under 1ppm) amount . (Unless otherwise noted, brown rice syrup, and therefore the dehydrated solids were converted using barley rather than a fungal enzyme.)
