True North Black Onyx (formerly Black Market) - Australian - Black Angus T-Bone. MB4/5 Grain-Fed

True North Black Onyx T-bone delivers the classic bone-in steak experience with a stronger emphasis on the striploin side, paired with a smaller, more delicate tenderloin. Cut from the short loin closer to the front than a porterhouse, the filet portion is more compact, while the striploin takes the lead in flavor and texture.

With MB4/5 marbling and a grain-fed program, this cut brings a noticeable increase in juiciness and tenderness, making it more forgiving to cook while still keeping a balanced, steak-forward profile.

Formerly known as Black Market, the Black Onyx program is recognized for consistent Angus quality, controlled feeding, and reliable marbling across all cuts.

What you're getting:

MB4/5 marbling – moderate-to-high fat for improved juiciness and tenderness
Grain-fed Black Angus – consistent texture and flavor development
Black Onyx program – premium Australian Angus with strong reputation
T-bone cut – striploin + smaller tenderloin, bone-in

What makes the cut special:

Two muscles in one steak — dominant striploin with a smaller filet
T-shaped bone enhances flavor and helps retain moisture
Slightly firmer, more flavor-driven than porterhouse due to smaller tenderloin
Naturally thick cut, ideal for proper searing and finishing

Ideal for:

Grilling or reverse searing
Cast-iron + oven finishing
Steakhouse-style cooking at home
Those who prefer more striploin than filet

Flavor & texture notes:

Striploin side: rich, beefy, with a buttery fat edge from MB4/5 marbling
Tenderloin side: smaller, soft, mild, very tender
Near the bone: deeper, more developed flavor
Overall: balanced but slightly more flavor-focused than porterhouse

This is a well-balanced T-bone — leaning toward bold striploin flavor while still giving you that tender filet contrast, backed by consistent Black Onyx quality.
