Use cattail as an emergency food
Cattail is one of the most calorie-rich wild foods on the continent — the 'supermarket of the swamp' — and edible in all four seasons.
Step-by-step
Positively identify cattail: tall bladed leaves and the distinctive brown hot-dog seed head. It grows only in shallow standing fresh water.
In spring, peel young shoots at the base and eat the tender white core raw or cooked like leek.
In late spring, boil the green immature flower heads like corn on the cob.
In summer, collect the yellow pollen by shaking flower heads into a bag and use it as a flour extender.
In fall and winter, dig the starchy rhizomes, peel, and either roast whole or crush in water to separate the starch.
Warning: Only harvest cattail from clean water. Cattail bioaccumulates heavy metals and agricultural runoff from polluted sources.
