Fenugreek leaves. Both the leaves and seeds are used, in the same way as they are for coriander (US: cilantro). The flavour of the seeds is improved by light frying. The leaves are very small.
Nigella. The small, black, bitter seeds of a relative of "love-in-a-mist". Nigella is often incorrectly called wild onion seed or black onion seed. The seeds have a sharp, pungent flavour with a hint of a smell of strawberries and are used for flavouring confectionary and liquors.
