Wattle – Of the thousands of varieties of acacia trees in the world, only a few have edible seeds. The Acacia victoriae and A. aneura are among the Australian species that are valued for their seeds. Their flavour has been likened to coffee, hazelnuts, and chocolate, and they are used in custards, ice cream, cheesecakes, and other baked goods. Wattle seeds are expensive because they are collected in the wild and require a labour-intensive process to make them ready for market, and because their demand exceeds their supply. They are available in Australian gourmet markets and specialty spice shops, but have failed to make much of an impact on the rest of the world.
