This hearty whole-grain soup originated in Minnesota, where much of the wild rice sold in the United States is still grown and harvested entirely by hand. It will warm up a winter’s evening in the best possible way. True wild rice is a dark brown seed harvested from rice paddies around the United States or in other countries. Since rice from different sources cooks at different speeds, watch for the grains to just begin to crack open and show the white interior, not completely split open and curl inside out.
