Waygu beef is a reasonably new variety of beef. It is heavily marbeled. It is this marbeling that sets this steak apart from all the others.The fat in the meat has more monounsaturated fats, This is positive for a lower cholestrol diet.
It is not cheap, a carcass will sell for $10,000 upwards. A burger in New York sets you back $40-50.

Burgers anyone.!! Using wagyu mince has turned me around in the humble homemeade hamburger.
First thing you notice it hasnt got that greasy feel some mince varieties give you. It forms the patties well and is very consistant in texture. So far I have not had a bad lot of mince labbelled Wagyu.
For USA readers I purchase Waygu mince from a small butcher shop in Brisbane at $10.99 AUD per Kilo (2.2 pounds)
I always use it fresh and only freeze the meat patties after making them.
I use olive oil or grapeseed oil to cook in.
Either outdoor BBQ or inside stove top is OK.
When using the BBQ regardless of time of day I must have a cold Aussie beer in my hand.
I will give you my simple yet effective healthy style Waygu Burger recipe.

Picture this a spring day late morning relaxing.
First open a beer and view main ingredients.

Prepare patties..

Into a bowl place Wagyu mince, add 1 egg half a cup of bread crumbs, pinch of salt, pinch of pepper, pinch of cayenne, dash of olive oil.

Stir with a chopstick until all is absorbed and meat begins to clump together in a even consistancy.

On a sheet of baking paper place a portion to suit place over it another piece of baking paper and flatten with your hand.

Once you have done this you are ready to cook.
First cook the eggs sunny side up until nearly hard, remove and place in warm oven or on side of BBQ.
