Cooking Method
Black Opal Wagyu, with its high-fat content, needs cooking techniques that allow this fat to render out, preventing an overly greasy result.
Pan-Searing:
1. Temper: Let the steak come to room temperature for about 30 minutes before cooking.
2. High Heat Sear: Heat a cast-iron skillet or heavy-bottomed pan over high heat. Sear the steak on all sides until it gets a rich, deeply browned crust.
3. Baste (optional): During the sear, add a knob of butter, garlic, and herbs (like thyme or rosemary) to the pan. Tilt the pan and baste the steak with the melted, flavored butter.
4. Rest: Remove the steak from the pan and let it rest for 5-10 minutes before slicing. Tenting loosely with foil helps retain heat.
Grilling:
1. Preheat: Prepare your grill for two-zone cooking – a hot side and a cooler side. Aim for a high heat zone around 230°C - 260° C (450°F – 500°F).
2. Sear: Grill the steak over direct heat, turning frequently, until a deep brown crust forms on all sides.
3. Indirect Finish (optional): If desired, move the steak to the cooler side of the grill, close the lid, and continue cooking until your desired internal temperature is reached.
4. Rest: Remove from the grill, tent with foil, and let rest for 5-10 minutes before slicing.
Sear then, Roast:
1. High-Heat Sear: Follow the searing instructions as in the pan-searing method.
2. Roast: Transfer the seared steak to a baking sheet and place in a preheated oven at around 180-200°C (350-400°F). Roast until your desired internal temperature is reached.
3. Rest: Tent loosely with foil and allow the steak to rest for 5-10 minutes before carving.
Tips:
- Thermometer is essential: The high-fat content of Wagyu makes judging doneness by touch unreliable. Use a meat thermometer, aiming for medium-rare (54-57°C) or - medium (60-63°C) for the best flavor and texture.
- Rendering is key: Searing over high heat helps render the fat, preventing greasiness.
- Slice against the grain: This ensures maximum tenderness in each bite.
Doneness Guide
Rare (48-52°C): Very red center, incredibly juicy and tender. Best for those who enjoy their beef quite rare.
Medium-Rare (54-57°C - Recommended): The ideal choice for most people, offering a beautiful balance of tenderness, juiciness, and a warm, red center.
Medium (60-63°C): The meat begins to firm up, with a slight pink center. Suitable for those who prefer their beef a bit less pink.
Medium-Well (65-68°C): Mostly brown throughout, with a very small hint of pink.
Well Done (71°C and above): Cooked through with no pink. Less juicy and tender than rarer options, especially with the higher fat content found in Wagyu.
Important Note: These are general guidelines. Cooking times can vary depending on your cooking method and the steak's thickness. It's always best to use a meat thermometer for accurate results.
