My yard has tons of dropped aerial tubers of true yams (I'm guessing Dioscorea alata and D. esculenta) that I don't want to sprout, hundreds of ripe pods of Velvet Beans (Mucuna pruriens), plus my huge plant of edible glochid-free Opuntia cochenillifera is now shading my back door veggies. Covered in salted water, they simmered a half hour or so, lid on, before cooling, were drained, then dumped into a big Pyrex dish. I love the yams huge underground tubers fried or boiled, but the aerial tubers have an unpleasant texture and musty taste. The chickens ate the cactus pads first, then the Velvet Beans, then the aerial tubers. Next batch I will add a LOT more cactus pads chopped small with a big knife on a cutting board. John
