Buy roasted, ground wattleseeds from Australian native specialists or a reputable spice shop. Whole, unroasted seeds are not usually available, as they are not useful in that condition.
Store in an airtight container away from light and it should keep for at least 15 months.
Tips & Tricks:
Add wattleseed to anything with chocolate, to biscuits (cookies), and even to meringue. It also blends well with spices such as coriander seed to impart a pleasant, barbecued flavour to meats, especially full-flavoured seafood such as salmon and tuna.
