Rump Cap vs Picanha: Same Cut, Two Names

Walk into a Brazilian steakhouse and the waiter carves picanha off a skewer at your table. Walk into a Sydney butcher shop and ask for picanha, and a good butcher will hand you a rump cap. Same cut. Same animal. Two names, and a lot of confusion in between.

That is the version you can repeat at a barbecue. Below is the part that actually matters when you are standing at the counter with money in your hand, and then the part that matters when it is on the fire.

Rump cap and picanha are the same cut

Picanha is the Portuguese name. Rump cap is what an Australian butcher will call it, and it is what you will see on a label here. In the United States you will hear sirloin cap or coulotte. In the UK it is rump cap too, sometimes picanha on a menu.

Anatomically it is one muscle, the biceps femoris, sitting on top of the rump with a thick layer of fat still attached. There is exactly one per side of beef, which is two per animal, and it has to be separated by hand. That scarcity is most of why it costs more per kilo than plain rump.

If a butcher does not recognise the word picanha, ask for rump cap with the fat on. If they still look blank, they probably buy their beef pre-broken into steaks and will not have it.

Where it sits on the animal

The rump is the hindquarter. The cap sits on the outside of it, right where the rump meets the sirloin, wrapped in its own fat layer. Underneath sits the rest of the rump, which is where rump steak comes from.

One cap weighs somewhere between 1.0kg and 1.5kg. That is a whole cut rather than a portion, which is why it works so well for a group and so badly for one person on a Tuesday.

Why the fat cap changes everything

As the cap renders, it bastes the meat underneath. You get beef that self-seasons while it cooks and a crust on the outside that no lean cut can produce. That is the mechanism, and it is why every instruction below points the same way: protect the fat, render it slowly, do not cut it off.

Rump cap and rump steak come off the same primal and taste completely different because of it. Trim the fat and you have thrown away the reason people book Brazilian restaurants.

How to pick a good one at the counter

Five things, in order of how much they matter.

1. The cap is still on and still thick. If it has been shaved back to a few millimetres you are buying an expensive rump steak. This is the one that ruins the most picanha.
2. The fat is white or cream, not yellow. Yellow fat is not automatically bad, it can just mean grass fed, but combined with a dull surface it usually means age.
3. The shape is a rough triangle with an even thickness. A cap that tapers hard at one end will cook unevenly.
4. The meat is deep red, not brown or grey at the edges. A little darkening on a cut face is oxidation and harmless. Grey through the muscle is not.
5. Ask how long it has been aged. Two to three weeks is normal. It does not need dry ageing, and paying for it here is not where your money works hardest.

Weight matters less than people expect. A 1.2kg cap feeds four generously with sides. If you are feeding eight, buy two rather than hunting for one enormous one, because oversized caps are usually oddly shaped.

How to cook picanha at home

There are two methods and they produce genuinely different results. Neither needs special gear beyond a barbecue or a hot oven.

Method one: whole cap

This is the one to start with. It is more forgiving, it looks like an event on the board, and it gives you the best crust to meat ratio.

1. Take it out of the fridge 45 minutes before you start. A cold centre is the main reason the outside overcooks.
2. Score the fat cap in a diamond pattern. Cut into the fat but stop before the meat. The scoring lets heat get into the fat so it renders instead of sitting there like a rubber lid.
3. Salt it heavily. Coarse rock salt, both sides, and leave it 30 minutes at room temperature. Salt is the only seasoning this cut needs. Pepper burns over high heat, so add it after if you want it.
4. Sear fat side down first over high heat. Ten to fifteen minutes, and do not rush it. You are looking for golden and actively rendering, not just coloured. Expect flare ups and move it away from them rather than fighting them.
5. Turn and finish over indirect heat, or in a 200C oven, to an internal temperature of 52C to 55C for medium rare. On a barbecue that is usually another 15 to 25 minutes depending on thickness.
6. Rest it 10 minutes, loosely covered. This is not optional on a cut this thick. Cut it early and the juice ends up on the board.
7. Slice against the grain, in thick fingers. The grain runs across the cap, so you are cutting the short way.

Method two: the steakhouse skewer

This is what you see at a churrascaria and it is worth doing once you are comfortable with the whole cap.

1. Cut the whole cap into 3cm to 4cm steaks, cutting with the grain this time.
2. Bend each steak into a C shape with the fat on the outside.
3. Thread two or three onto a skewer, fat edge facing out.
4. Grill over high heat, turning so the fat edge gets direct heat, about 12 to 18 minutes total.
5. Shave the outer cooked layer off with a sharp knife, serve that, then return the skewer to the fire and repeat.

The skewer method gives you more crust and less pink, and it feeds people in waves rather than all at once. It is a better party method and a worse dinner method.

Doneness temperatures

Pull it off the heat at the temperature below. It will carry over another 2C to 3C while it rests.

Buy a probe thermometer if you do not own one. On a cut that costs this much, guessing is expensive.

Five mistakes that ruin it

Trimming the fat cap. Covered above, but it is worth saying twice. People do it out of habit.

Slicing with the grain. Look at the muscle fibres before you cut. They run the length of the cap, so your knife should run across it.

Cooking it from fridge cold. The outside overcooks while the centre catches up.

Not resting it. Ten minutes minimum. Twenty does no harm.

Adding marinade. This is a cut with enough flavour of its own. Salt, fire, time. Sugary marinades burn before the fat has rendered.

Picanha or rump steak: which should you buy?

Buy the rump cap when you are feeding four or more and you want something that looks like an occasion on the board. Buy rump steak when you want a quick midweek steak for one or two.

Per kilo the cap costs more, but you are paying for a specific muscle that has to be separated by hand and there is only one per side of beef.

What to serve with it

In Brazil the answer is farofa, black beans, rice and a sharp vinaigrette of tomato, onion and parsley. That vinaigrette in particular is worth copying, because the acid cuts through rendered fat better than anything else on the table.

If you are not going down that road, keep it simple. Potatoes roasted in beef fat, a green salad with a sharp dressing, and good bread to catch the juice off the board. Chimichurri works. Heavy cream sauces do not, because the cut already brings its own richness.

Cold picanha sliced thin is better than most leftover steak because the fat keeps it moist. Warm it briefly in a pan with the pan juices rather than in a microwave, which will make the fat greasy.

Where to buy picanha in Sydney

Most supermarkets do not carry it. The cut gets broken down into rump steaks before it ever reaches the shelf, because rump steak sells faster and takes less skill to prepare. You need a butcher who breaks down whole primals.

We cut rump cap in the shop at Mortdale, cap on, and we will trim it to whatever thickness you are cooking to if you tell us the method. Order online for pickup or delivery across Sydney, or come in and we will talk you through it at the counter.

If you are cooking the whole cap, render the offcuts rather than binning them. Our beef tallow is made exactly that way, and roast potatoes cooked in it are the best thing you will do with a leftover.

Questions we get asked

Is rump cap the same as picanha?
Yes. Picanha is the Portuguese name and rump cap is the Australian butcher's name for the same muscle.

Should I trim the fat cap?
No. The fat renders and bastes the meat, and it forms the crust. Score it, do not remove it.

How do I slice picanha?
Against the grain, in thick fingers, after resting it 10 minutes.

What temperature should picanha be?
Pull it at 52C to 55C for medium rare. It will carry over to 55C to 57C while resting.

How much picanha per person?
Around 250g to 300g raw weight per adult if you are serving sides. A 1.2kg cap comfortably feeds four.

Can I cook picanha in the oven?
Yes. Sear the fat side in a hot pan first, then finish at 200C to temperature.
