Manioc, also called cassava, is a starchy tropical tuber. Ground and dried, it becomes manioc flour—what tapioca is made of. Manioc flour is often sprinkled over feijoada to thicken it and add substance and crunch. More Recipes From Eric Ripert
Melt the butter in a large skillet. Add the onion and cook over low heat until softened, about 7 minutes. Stir in the egg and cook, stirring, until dry and crumbly, about 30 seconds. Add the manioc flour and cook over moderate heat, stirring occasionally, until lightly toasted, about 8 minutes. Stir in the parsley and season with salt. Serve with the feijoada.
The toasted manioc flour can be prepared earlier in the day and reheated.
Manioc flour, or cassava flour, is available at Latin markets.
