Manioc root doesn't differ much from other starchy vegetables when it comes to cooking other than its preparation, but does best when you make the most of its texture. Although starchy like potatoes, manioc -- or cassava root or yuca, depending on where you are -- has a fibrous texture that doesn't quite go away after boiling. For something softer, you can steam-fry it, or steam then saute it in the same pan. You usually find sweet manioc root in American markets, which isn't actually sweet unless you compare it to bitter manioc root, a different variety found outside the U.S.
Prepping Manioc Root
Slice off the tapered ends of the manioc and cut it crosswise into 3- to 4-inch-long segments using a sharp, heavy kitchen knife. Peel the thick, fibrous skin using a paring knife.
Stand the manioc upright on the work surface and cut it through the center into quarters. Slice about 1/4 inch from the sharp-angled edge of each wedge -- the part that was in the center of the root -- and discard it. The part you're cutting off has a tough, woody texture and a slightly darker color than the rest of the flesh.
Cut the manioc into 1/2- to 3/4-inch pieces and rinse them in a colander. Keep the sliced manioc covered with water in a bowl until you cook them.
The Steam-Frying Method
Heat few tablespoons of oil or butter in a pan on the stove over low heat. Drain the sliced manioc and add it to the pan in an even layer.
Season the sliced manioc to taste with salt. Pour enough stock or water to cover the bottom of the pan, or about 1/8 inch deep. Cover the pan.
Steam the sliced manioc until tender, about 20 minutes. Take the lid off the pan and set the heat to medium-high.
Stir the sliced manioc frequently when the water evaporates from the pan, and fry until crispy and golden brown on all sides, about 5 minutes. Serve immediately for the best taste.
Boiling Sliced Manioc Root
Drain the manioc after cutting and rinsing it, and add it to a pot. Cover the slices with a few inches of water and add salt to taste.
Boil the sliced manioc until fork tender, about 20 minutes, and drain.
Add boiled manioc to stews and soups in the last 10 minutes of cooking, or mash it like a potato and add milk, butter and seasoning to taste.
