A yam is a tropical root vegetable that looks like a potato and thrives in warm climates. Yam flesh can be white, yellow, pink, or purple in colour, and has a sweet, bitter, or insipid flavour. The acrid essence in most yams is dissipated during cooking. Yams are starchy veggies that are cooked. They're frequently boiled before being mashed into a thick paste or dough. Yams can be cooked, boiled, mashed, shredded, or sliced into chunks, just like potatoes.
