Chia seeds come from a species of flowering plant called Salvia Hispanica. It is native to Mexico and Guatemala and is supposed to have been cultivated as a food source by the Aztecs in pre-Columbian times. In fact the name chia has a little mystery attached to it, as it comes either from the world for “oily” in the central Mexican Nahuan langauge, or from the Mayan word for “strength”. Either way, both are accurate descriptions of the nutritional punch these little seeds deliver.
The seeds themselves are small, around 1mm in diameter and range in colour from greyish brown to black and white.
They can be eaten raw or cooked but a slightly more unusual property of the chia seed is that it can absorb large quantities of liquid. This is often water, but fruit juice can also be used.
They have a mild nutty taste, which tends to complement rather that over power the foods they are added to.
