Chapter: Vegetable Recipes
Get the roots of the cattails. Peel away tough leafy layers to the tender
core, about 1/2 inch in diameter and maybe 12 inches long. This can be
eaten raw, like celery, or sliced into a salad. Or, cover the cores with
boiling water and simmer about 10 minutes. You may pick the green bloom
spikes of the cattails, remove sheathes, and boil in water until tender,
and eat like corn-on-the-cob.
