The Jakarta Post tried three different lesser known beef cuts, aged as follow:

Picanha

Being a Brazilian cut, it can be found in churrascarias or certain specialty steakhouses. Picanha is a rather small cut of meat on top of the sirloin, usually called rump cover or rump cap by Americans. It has layers of fat, and as it is not a muscle that moves much, it remains tender. The Post tried the picanha at AB Steak by Akira Back Jakarta, where it was of 9+ grade marbling and dry-aged for 21 days.

According to Joel Lim, executive sous chef of AB Steak, the picanha can be aged for up to 100 days. The more it is aged, the better the taste. Chilled to a temperature between 2-5 degrees Celsius during the dry age process, the grilled picanha is already flavorful with only a little bit of salt and pepper.

Rib-eye

The tenderloin may be the most tender cut, but the rib-eye is juicier, more flavorful, with just the right amount of fat. Joel said that it was the most balanced beef meat, when he presented a 60-day dry-aged rib-eye for The Post. The meat was still attached to the bone, which helps prevent the meat from shrinking during the dry ageing process.

The rib-eye's tenderness comes from the fact the cut's muscles don’t get much exercise. The best muscle the cut has is the spinalis dorsi, aka the rib cap, from the curved top of the meat. It lies just above the main muscle of the rib-eye called the longissimus dorsi. Although the main muscle is the part where the intramuscular fat (marbling) tends to deposit, beef connoisseurs consider the spinalis dorsi to be the better one.

Tri-tip

There are only two of these cuts in a cow, so consider yourself lucky when finding one. Mark Bittman wrote in The New York Times that this ultra-thick, nicely marbled, strongly flavored steak was perfect for roasting, broiling, or a combination of stove-top and oven cooking.

Often going by many (often incorrect) names such as the California cut, Newport steak, top sirloin and more, Mark prefers the term tri-tip, because the steak is triangular and is the tip of the sirloin.

The tri-tip served to The Post at AB Steak had gone through a wet-ageing process, in which the beef was vacuum-packed in plastic and aged in a refrigerator. The meat was then packed in its own juices, with its natural enzymes breaking down the connective tissues so that it became tender, resulting in a melt-in-the-mouth texture after grilling.

All lesser known beef cuts served to The Post that evening came with a unique dining experience. They were grilled and carved by the chefs on our table. The meat could be eaten straight after it was grilled, with no unnecessary resting as occurs when it’s transported from the grill in the kitchen to the table.
