Supermarket Morrisons is launching a huge 42oz steak that you can tuck into for £15.

The Tomahawk steak, weighing 1.2kg if you prefer it like that, is the biggest steak available from a British supermarket and will only be available between Thursday and Father’s Day.

This mighty meaty feast, aged for 14 days and sold with the rib bone intact for enhanced flavour, weighs more than six times the average cut.

It is called the Tomahawk because it resembles the large native American axe.

Morrisons butchery expert Darren Spauls said: “The Tomahawk will offer dads this Father’s Day the ultimate carnivore experience. However, if you can’t defeat the beast alone, the steak will serve two to three people.”

He recommends cooking the steak by frying and sealing it first, for around three minutes each side, before browning in the oven for a further 25 minutes for a medium steak.

He added: “We’re sure that jaws will drop when customers see the Tomahawk at our butchers counters.”

The slab of steak measures 14 inches long and eight inches wide on average, and a similar lump of meat would set you back £77 at a London restaurant.
