Description
Cooked seeds are used by various indigenous North American tribes as a staple food. They have a bitter taste and can be dried, ground into a powder, and used as a thickening agent in dishes or mixed with grain for bread. The seeds contain bitter tannins, which can be removed by thorough washing in running water, although this can also remove minerals. The whole seed or the ground powder can be used. One method to remove tannins more quickly is to place them in a cloth bag and submerge it in a stream. A simple taste test can indicate when the tannins have leached out. Traditionally, the seeds were buried in moist soil to germinate, after which they were dug up in the spring for use. Roasted seeds serve as a coffee substitute.
