Most people I think associate Wagyu with Kobe Beef and don't realize the difference.
I use Pick N Save 93% and purchase when on-sale for a $6.90/#. This week I had a coupon for an additional $1 off.
For burgers, I toast the bun in butter, add a cold butter pat into the center of the burger and a soft pat onto the bun for a real Wisconsin 'Butter Burger'.
For real Japanese A5, I purchase from Mitsuwa.
I purchase no Wagyu at this time.
I have had Wagyu briskets and Tenderloins from Snake River Farms.
They were very good.
One brisket was smoked with a Tex-Mex seasoning and one of my friends pronounced it "the best brisket I have ever tasted!".
But Wagyu ground beef, I think not!
