Picanha is a very special cut of beef. It is taken from the rear of the stock and is covered in a delicious layer of Fat. It is also called Rump Cap in the UK and is hard to find.
Brazilians love to buy Picanha for the taste and the fat and season it with salt and herbs. It is especially nice when cooked on the BBQ.
English people use it as the basis for a Roast and even a small piece in the over will swell up in size as it cooks, giving the best beef joint for a Sunday Roast.
It can be expensive and this is due to its quality and short supply, but if you want the best beef, then this is it.
