Reverse Information: JACK-IN-THE-PULPIT, INDIAN TURNIP (Arisaema triphyllum) - Uses: Roots only; breads, chips. The walnut-sized corm must be throughly dried to neutralize the calcium oxalate. The tiniest taste of the raw corm will set the tongue on fire as it is EXTREMELY peppery. Dry for 72 hours in a slow oven. Then grind it into a cocoa-like flour to add to breads and cookies. Or slice the root thinly and dry in oven or let it dry naturally for several months, then use like potato chips with dip.
