Whole Organic Cumin/Jeera Seeds come from Cuminum cyminum. A popular culinary spice from ancient times. Jeera has a very aromatic flavour which gives a totally distinct taste to the dishes. The strong aromatic smell is present in it due to the presence of volatile oil which is about 2 to 4 percent. It is mainly a mixture of cymol or cymene and cuminic aldehyde, or cyminol, which is its chief constituent.
