*If you only have unseasoned panko (or breadcrumbs), you may absolutely use them. Simply add a little more salt to taste…I’d add ¼ teaspoon and then supplement with an extra sprinkle when serving, if needed.
One standard slice of bread (1 ounce) will yield approximately 1/2 cup of fresh bread crumbs. Loaf bread, English muffins, even pita bread or bagels may be used. Break the bread in pieces and pulse in a food processor, mini chopper, or even a coffee or spice grinder. For a low-tech method, rub stale or toasted bread against a grater. You will get best results if the bread is either stale or toasted. Extra may be frozen for future use.
If your pecan pieces are not finely chopped, pulse them in the processor or chopper as well. You want some texture (as opposed to sand or fine-crumb consistency) without big chunks. The pecans can also be minced by hand.
