I purchased Petrale sole fish at 99 Ranch Market for $1.99 lb. I was surprised usually I pay $7.99 or $9.99 per lb at other markets. I also was told by the seafood clerk at 99 Ranch that Petrale is the same fish as Rex sole. I fried the fish with cornmeal and flour as usual, the fish was mushy and broke apart while cooking, the worst fish I've ever eaten, had to throw away. I'm not sure what I purchased.
