In a small skillet over medium low heat, melt the butter.
Add the breadcrumbs and toast until golden, stirring occasionally.
Next, add the garlic and cook for one minute, stirring constantly to prevent burning.
Remove from the heat and add the parsley, zest and big pinch of kosher salt. Stir well to combine. Serve on top of browned butter, celery and leek pea puree (see notes for recipe) or seared scallops with white wine lemon pan sauce (see notes for recipe)
