In a small bowl, soak gelatine in 1/2 cup cold water for 5 minutes. Stir in 1 cup boiling hot chicken broth, garlic powder, and green onions and celery seed (if using).

Pour mixture into 8 individual sized moulds (silicone works well) or 1 large one. Chill for at least 3 hours.
Just before serving, dip mould into hot water for less than 10 seconds, then invert onto serving dish.
