These are little green-coloured seeds that have a most amazing fresh aniseed flavour. Fennel seeds are used as a major component in Chinese 5 spice and in Mukhwas in India, a mix of nuts and seeds that is served after a meal to help freshen breath and aid digestion. Their flavour works incredibly well with pork and fish, and the seeds can be added whole or ground to really lift their flavours. In a cool, dry, dark place, the seeds will last about one year. The ground spice will last under six months.
