This is a really satisfying Afro-Brazilian dish which everyone seems to love. It has an extremely subtle yet unique flavour and texture quite unlike any other. Palm oil can be found in the world foods section of any major supermarket and is essential for this dish, as is the cassava which you may find under the name mandioca or yucca root. Yucca root is a long root vegetable that looks like a wooden stick, I have seen fresh Yucca root in the exotic veg section and in the frozen veg section in some UK supermarkets. If you can't find these 2 ingredients at your local supermarket you will most certainly find them at any ethnic supermarket. The finished product has a tropical feel to it and is quite colourful. The lime is mandatory here too as it cuts through the fats and lifts this dish right up. Absolutely Gorgeous.
