Common gardeners may know the plant as Live oak. Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Quercus wislizenii Common Name: Live oak Family: Fagaceae Author: A.DC. Known Hazards: None known Mature Height: 20 Mature Width: 30 Habitat: Desert mountain slopes and valleys below 1600 metres[71, 229]. No more than a shrub in the desert, forming trees in the sheltered coastal valleys[82].
Edible Uses: Seed - cooked[105, 161]. A staple food of some native North American Indian tribes[257]. It can be dried, ground into a powder and used as a thickening in stews etc or mixed with cereals for making bread. The seed, which can be up to 35mm long and 1cm wide[82, 229], contains bitter tannins - these can be leached out by thoroughly washing the seed in running water though many minerals will also be lost. Either the whole seed can be used or the seed can be dried and ground it into a powder. It can take several days or even weeks to properly leach whole seeds, one method was to wrap them in a cloth bag and place them in a stream. Leaching the powder is quicker. A simple taste test can tell when the tannin has been leached. The traditional method of preparing the seed was to bury it in boggy ground overwinter. The germinating seed was dug up in the spring when it would have lost most of its astringency.
The roasted seed is a coffee substitute.
