The rump cap (also known as sirloin cap or coulotte in the USA) is a wonderful, under-used cut of beef here in the UK. A thick cap of fat runs across the top which, when cooked properly, adds a beautifully rich depth of flavour to the meat. A very popular cut in Brazil, it is known as ‘picanha’ and is commonly barbecued on spits. The layer of fat constantly bastes the meat as the skewers rotate, giving a flavourful, caramelised result.
The rump cap, as you may be able to guess, comes from the top of the hindquarter of the cow. It is not as tender as some cuts, but cooked with the right care and carved properly, it can be a very succulent cut that is full of flavour. When buying rump cap, make sure you have at least a 1.5cm layer of fat attached.
