Went to my favorite Costco on Sunday morning and they didn't have them. Came back and cooked frozen, (thawed in refrig for two days) prme states that I bought in late Feb at C's for $12.99 a pound, and after letting them stand on the countertop, seasoned for two hours, two minutes a side sear at 500 and cook then turn off the burner and cook at around 400 til 125 centers at indirect, let stand for 15 minutes then bon apetite. Could cut with a butter knife and superb flavor.
Indescribably delicious.
