BenefitUse Food: Native people gathered the thick rootstocks in winter and spring, boiled or roasted them for several hours, then peeled them to expose their sweet, gluey contents. Rootstocks were also sliced, dried and ground into meal or flour. The starchy seeds can be difficult to remove, so the tribes rotted the fruits until the pods became soft. The heated seeds swell like poor-quality popcorn, making a crunchy snack. (Kershaw)
