Chermoula. "Chermoula is a bold, garlicky, spicy sauce and marinade used all over Algeria, Morocco and Tunisia to spice up not only fish and seafood, but also poultry, meat and vegetables." There are two recipes here....one for oily fish (this would include Algerian sardines) and one for white fish.
I like the idea . It would really look good with a couple mounts of your favorite fish species . Crappie , Largemouth , Smallmouth , Hybrid Stripper , white bass , or several species of trout. it would also look good to with several vintage lures .
