Everyone loves trying something new on their barbeque to impress friends and family and upstage the neighbours. And what better way to go gourmet than to serve up some delicious Welsh Lamb? Our step by step guide on how to butterfly a leg of Welsh Lamb will help give you the perfect cut that cooks easily and quickly on the coals, while giving you a tender and tasty meat.

How to Butterfly a leg of Welsh Lamb

Step 1: Trim outer skin / fat

#

Using a sharp knife with a fairly long blade carefully remove most of the outer skin, and if there is a fair bit of fat - remove some of the fat. This stage, though not essential, will allow the marinade to penetrate the flesh more resulting in even greater flavour!

Step 2: Cutting out the bone

#

Turn the leg of lamb over with flat side on the board. Run the knife around the curved bone that protrudes from the wider end of the leg. Slit into the leg as close to the bone as you can. Try not to hack the meat!

Step 3: Remove the bone

#

Cut around the bone carefully until the bone is exposed and you can cut under it to remove it. You will need to twist and pull it a bit to get the bone out.

Step 4: Remove the knuckle bone

#

You’ll also find another bone – Knuckle bone, on the narrow end (shank end) of the leg. Run the knife around the bone to loosen it, twist and pull out the bone.

Step 5: Slice into the meat

#

Open/ spread out the boned leg of lamb, and remove any excessive pieces of fat if there are any. Carefully make a horizontal slice into thick part of the flesh, but making sure not to go all the way through. Do this on both sides.

Step 6: Finish

#

Open out the leg and flatten to resemble a butterfly shape. This should result in a fairly uniform piece of meat.

Final cooking instructions

You are now ready to place the meat into your marinade – leave for a few hours or preferably overnight to ensure it absorbs the flavours of the marinade.

If cooking on the BBQ it’s easier to handle and cook if you thread a few long metal skewers through the meat to hold it open and flat.
