Never had quill back myself, I will keep it in my mind though. The sturgeon is suer critical that you remove all that red fat or it kills the subtle flavors. I roll it in four with salt, pepper, and cayenne and a little dill. Then egg bath, roll in panic, ten minutes in the freezer on cookie sheets, then fry until it floats. Homemade tarter and MALT VINEGAR you know it!
